I agree with the sentiment (and you've seen how small and light my scooter is) but I can totally understand why people buy larger/stronger vehicles for safety. Unfortunately, it becomes an arms race: I'd feel perfectly safe in one of those egg cars if _everyone_ had one. As it is, though, I'd be really worried about driving one because I would be more vulnerable than in a traditional car, but much less able to take evasive action to avoid collisions (vs. my scooter).

Having said that, I'm writing this on the bus, which can take me to most places in Beijing if I'm not in a hurry.
