Autobesity epidemic - is bigger always better?

A cold day today. For the first time this year it feels like a typical New England winter. Of course, this means that if you need to get anywhere, you should probably drive. Roads always get plowing priority in America and bike lanes or sidewalks are now used for snow storage.

If you've driven to work today, chances are you were sitting inside your comfortable, over-sized SUV, starring at a large infotainment screen on your dashboard. Before work you wanted to grab a cup of coffee at your favorite cafe but there was no place to park your truck, err... I mean, car. Most parking spots were gone since they put that stupid bike lane there and the only ones left were too small for your new SUV. You gave up on coffee and drove straight to your office instead, bitching on the way that "Whoopi Goldberg was right and this city is going to hell".

Apparently, that's what some New Yorkers thought as well posting these home-made signs in the middle of street and announcing that now bike lane on 12th Street is cancelled because it "only benefits other people".
I see. So whoever posted these signs is trying to tell us that since he/she doesn't use bike lanes, they are not needed. Great! Now we can officially "cancel" all senior centers, retirement homes and baseball stadiums - it's because I don't have any use of these facilities and they "only benefit other people".

This is exactly the kind of antisocial behavior we have to daily deal with here in the United States. It's always about "me" and not "us". This is why we don't have good public transport, national health care, public kindergartens, etc. Basically we are acting like a bunch of selfish idiots on a desert island.

But at least we have something great. I mean, literally great - giant cars.

During the last 4 years SUVs have surpassed sedans as the best-selling vehicles. Essentially, what we have now is "autobesity epidemic" in this country.
You may think - "So what? These cars are safer, right?" Well, they are - but only for those inside. For everyone else, large and heavy SUVs are just much more dangerous. If you're a driver of a small sedan you are unlikely to survive a collision with giant SUV or a pick-up truck. The difference in mass and kinetic energy is substantial so your logical decision is to buy a SUV as well. This leads to an "arms race" and soon everyone will be driving large SUVs around.

Unfortunately, things look even worse if you like to walk or ride your bike instead. That's because big cars kill. The hoods are so much higher above the ground, compared to a small sedan that drivers simply can't see anything right in front of their cars.
These problems are evident in numbers. Here's a couple of charts I stole (or borrowed) from  Twitter. As you can see, "between 2010 and 2016, the number of US pedestrians killed by cars went up a staggering 39%":

Which can be attributed to more and more large cars (SUVs and similar) being sold.
Of course, that's not the only reason why more Americans drive in traffic collisions. Driver's distraction is certainly another factor. It's not the news anymore that drivers look at their cell phone screens more than they look at the road ahead. And if they drive a giant car, they might not even know they hit you. When they do - they will just drive away and issue some ridiculous apology later on.

But it gets worse. As we have seen on the last Consumer Electronics Show, car manufacturers plan a very bright future for us. It's going to be bright from all those screens placed in front of drivers eyes. Apparently, car makers think that today's drivers are still not distracted enough with their cell phones and it's perfectly acceptable to place a widescreen TV on the dashboard and an iPad on the steering wheel.
Byton's prototype for the "dashboard of the future".

I hope something like this will never become legal but on the other hand, I'd be fine with it, but only if these screens were disabled when car is moving, when cars finally come with systems that disable cell phones inside moving vehicle and when cars would automatically slow down to 10mph when you take your eyes off the road.

Unfortunately, I realize that's not what most people would want to buy. Instead, we are entering a post-jaywalking era, when pedestrians would not necessarily be blamed for just crossing the street, but for either "distracted walking" or... not wearing appropriate sensors!

This was a big news at CES too - something called C-V2X technology that makes vehicles smarter. It allows cars to communicate with each other, possibly avoiding collisions. Sounds good? Maybe. The problem is - pedestrians, bicyclists and dogs do not have built-in C-V2X sensors and that would make them invisible to these automated cars.

While it may look bad now when media is reporting that a cyclist hit by a truck wasn't wearing a helmet (thus implying victim's fault), soon we may see reports that "pedestrian wasn't wearing a C-V2X sensor" and that wasn't driver's fault even though he was playing Fortnite on his steering wheel-mounted iPad.
I certainly hope that's not what the future really brings.

Building a perfect commuter bike

And just like that it's nearly mid-January, yet winter remains somehow... undecided. On one hand, the lack of snow means less shoveling. On the other, my kids complain and keep asking when will the snow come.

The wet season with frequent rain/snow mix and road salt sprinkled all over "just in case" means that my bike requires frequent cleaning and chain maintenance. Because of this I started pondering about a hypothetical "what-if" scenario - if I could build a perfect year-round commuter bike, what would it look like?

Of course, a year-round commute means something very different depending on where you live. Those of you lucky to reside in the sunny Southern California may never need fenders, not to mention studded tires. But since I'm spending my winter in New England, let's focus on an all-weather bicycle.

Frame and fork
If I could afford it, my top pick would be a titanium frame, simply because it's virtually indestructible by elements. It doesn't rust so it doesn't need paint and any scratches can be simply buffed out with some fine grain sand paper. My second choice would be likely either a well-protected steel or even aluminum frame.
Titanium frames last a lifetime. Even when covered by road salt.

Regarding the fork, a rigid fork is all I would need. Suspension is really unnecessary in the city and just adds weight and complexity.

I would want the fork and frame to have all possible mounts for fenders, racks, lights, etc. Internal routing for electrical wires is certainly a good idea too.

Wheel size
Wheels for my ideal commuter bike would be certainly build around 700c rims but I think that the 26" MTB standard could also work quite well. The worst choice (apart of some tiny 16"-20" wheels) would be the more-and-more popular 650b format. Why? Well, it's all about...

Tires
Basically tire choices would determine what wheels I consider using and the major limitation comes from studded winter tires. There's plenty of them available in 700c size but studded, urban tires (i.e. without a very aggressive off-road tread) are essentially non-existent in 650b size. In general the 700c standard seems like the best choice - I can choose from everything starting at 23mm wide road slicks to a massive 3" wide MTB rubber, although I think that 35-38mm wide tires are likely to be the most optimal.
Studded urban tires - readily available in 700c size.

Drivetrain
This is the part that gets really messy and as such I would want to make it somehow impervious to dirt and mud. It seems to me that the best solution would be to use an internally-geared hub such as the 8-speed Shimano Alfine with a belt drive. This combination means that all gears are enclosed, with no chain cogs requiring frequent cleaning. The belt is completely maintenance-free and since it's running dry, it also means that no oiled, moving parts would be exposed on my bike. While some of you would prefer to just use a singlespeed, fixed drive, I like having at least a few gears to my disposal.
Internally-geared hub with a belt drive - the best choice for winter commute in the city.

Brakes
I would go with hydraulic disc brakes on such bike, simply because they provide plenty of power and modulation in all conditions. Also, they do not wear out rims like caliper brakes do. Being fully hydraulic they are also immune to any water ingress into cable housing (since there are no cables) so I can be pretty sure they will remain operational in our New England winter.

Shifters
To change gears I would prefer using a twist-type shifter (unlike a trigger type). It's simply because a twist shifter can still be operated with thick winter mittens (or finger-less gloves) on hands.
Twist shifters - usable even in thick winter mittens.

Saddle
The saddle on my bike would be likely from Brooks. They are made out of leather and aren't really maintenance-free (need to be protected from being soaked in rain) but provide supreme comfort that's hard to give up.

Pedals
Definitely not clipless pedals, since my commute isn't a race and I prefer riding in my work shoes to work. A simple, wide platform pedals would do the job. As a bonus, I would pick ones made out of plastic or some composite, but not aluminum. That's because metal pedals tend to act like heatsinks at low temperatures and cool down my feet too much.
Plastic/composite platform pedals - plenty of grip and "warmer" than all-metal options.

Accessories 
Full-length fenders are absolutely essential on commuter bike as well as at least one cargo rack. I would prefer a front rack and/or a basket, as that's the most convenient way of carrying an office bag or any smaller load on a bike. An additional rack in the rear could be useful for those larger grocery runs.

Finally, my super-commuter would certainly have both front and rear lights powered by a dynamo hub. This way I would never need to worry about spare batteries. My top choice for a headlamp would likely be a German-made Edelux, as it has a properly-shaped beam that doesn't blind other road users in the city.
SON Edelux - pretty much a golden standard for a proper bicycle headlight.

The last items that are likely good to have is a decent, stable dual-leg kickstand and an integrated rear-wheel lock.

That's pretty much it. What would your ideal commuter bike look like?
