Which is what's caused a size-war with cars. Your own safety by being the bigger car comes at a detriment to someone else's safety, and as cars, especially trucks, have gone off the deep end in this regard they've become downright negligent.
I say this as a benefactor of the bigger-car-wins situation, as my father is still with me by virtue of being in the bigger car recently. It's selfish but it's also sensible if everyone else is going to be in a bigger car, and so I think it's something that could only be curtailed by regulation.
If you're comparing a new Camry to a 1970s Cadillac, sure. Sizes have increased within each product line (see original mini -> modern mini, porsches) and the types of vehicles available in each niche have also grown larger (Scion xB -> kia soul, Toyota pickups -> f150s). The overall trend has been for increasing sizes.
