In general: whoever's in the smaller car, comes off a whole lot worse. Driving something the size of a tank is good for you.
And bad for everybody else. Total utility is probably negative because the process where people drive larger and larger cars in order to be safer (at the expense of others) leaves everyone roughly equally safe, but driving more expensive, more fuel-hungry, less-manoeuvrable cars.
Whether this is reason not to buy a larger car depends on one's level of altruism, of course.
"A Nice Morning Drive" is a (very) short story that takes place in a future where this process has been taken to an extreme. (It was the inspiration for Rush's song "Red Barchetta".)
The Singularity Institute is hiring an executive assistant for Executive Director Luke Muehlhauser.
Right now his limiter (besides the need for some sleep and recreation) is not (1) cognitive exhaustion after a certain number of hours or (2) akrasia, but instead (3) needing to spend lots of time doing things that don't need to be him: e.g. hunting down the best product for X and buying it, shopping for food, finding names and email addresses for the top 30 researchers in field X, finding motorcycle classes and a motorcycle so he can stop paying so much for cabs when he doesn't have time for public transport, scheduling meetings with dozens of donors and collaborators, finding a good location for activity X, preparing an itinerary and buying plane tickets, and hundreds of other small things. (Some of these are 'life' things, some of these are SI things, but hours are hours.) Luke may also ask his executive assistant to handle certain tasks for other SI staffers.
