Also, the distances between cities in the US is far greater than what it is in EU nations like Germany or Italy. Plus the scenery is much better. Ever ridden across North Dakota?
Assuming you live in Europe. It's different in the US.
Some people do legitimately have a need for larger vehicles. The farmer I use to work for had 4 or 5 F-150s to be used on the farms (no way you are getting a regular car in and out of some of those waterlogged fields). Those were farm equipment, not something you use to drop off the kids at school. People who need vehicles like that to go grocery shopping are an extreme minority.
And I have never seen any of the roads around here closed, even when impassable by anything short of a snowmobile or a tractor.
2. Wasn't that image on a Photoshop hoax site?
3. That path is perfectly clear. Try driving a car with 4" of clearance through 8" of snow. It can be done with very good snow tires, but not nearly as quickly as a vehicle with more clearance.
2. I do not believe so.
3. This is true. You have to clear the roads for people to use smaller cars.
If U.S. cities had proper cycling infrastructure, I would expect many more adults would use bikes for local travel. But as it is, driving is certainly more reasonable for many people when the alternative is biking on a shoulderless road with deadly vehicles passing inches away from you.
Lucky for me, I live near the most bike friendly city in the country - and it's not on the left hand coast. ;)
If it was feasible and I lived within 10 miles of where I work, I would for sure bike. Right now, I commute almost 20 minutes in my car, so biking to and from work just isn't a great idea. If I lived and worked in the city, I would for sure bike every day. Even if I worked in the city, I would utilize the light rail for the majority of my commute. It sucks I would still have to drive 10-15 minutes to get to the light rail though.
