Not even close, but that's not so bad. ICEs will probably always have their place but most people can go without, especially in Europe (Americans are very loud about how they need to drive 3000 miles to work everyday so I won't bother arguing that)

You can fit an entire Italian town in the size of a freeway interchange in Houston:

Our cities were designed to be spread out to make them less susceptible to atomic weapons in the 1950's (not a joke).

So... Yes, we need cars. It really is a long way for many of us.

Granted, not to take away from the point of different use cases, however Sienna is a very small medieval-era town that one can walk across at leisure and the Houston interchange is one of the most complex in the US. So it is somewhat of a hyperbolic comparison.

I agree that very common suburban and rural vehicles, respectively, are SUVs and pickup trucks. But I am curious what portion of urban drivers use a vehicle that most of the time far outclasses their average use case. I would like to find data on this but it seems to me like often people own a vehicle for the extreme outlier use case.

Why would you want a vehicle that only covered 95% of your use cases?

It's like condoms - better to have it and not need it than need it and not have it.

It certainly makes sense on a personal level but when one multiplies this thought process by a given population there starts to be a compounded issue of excess material going into the construction of the vehicles, excess fuel being used to move them, and excess parking space used to store them, to name a few.

Redunancy and efficiency are common tradeoffs we are constantly trying to balance. It's only a question of how important the effects of downsides are.

Sometimes someone dies as an immediate result, and for some it means waiting for another 5 minutes.
