Keeping the proper safety distance to the car in front of you is surprisingly hard. On the one hand, it goes against the learned behaviour (of most people). On the other hand, other drivers' bad behaviour actively sabotages this by overtaking and/or squeezing in the spaces that open up from proper distance. Most drivers just don't have the emotional control to drive well, but the actual problem is they don't even realise they're bad drivers. SUVs are the completely wrong solution to this problem. I'm not sure if distance warning (akin to seatbelt) beepers could help, but I suspect people would hate them so much it'd doom sales.
