I don't disagree that there's an aspiration towards larger cars for safety, but only part of that is *because other people are getting bigger cars". Drive into any UK city today and you'll be sharing the [often quite small] roads with 44 tonne lorries, 18 tonne buses, and LGVs and vans you'd need a ladder to see over. People feel safer in bigger cars in cities because the roads are so unsafe. To break this spell we have to have hard size limits. No HGVs in cities, permits and height limits for commercial vans in urban residential areas (no vans and trucks as primary vehicles), and nothing bigger than a (wheelchair accessible) Citroën Berlingo on residential streets otherwise. This won't reduce much traffic but it should make it a lot smaller.
