You forgot: c) lots of people would cry 'fowl' citing massive carnage on the highway as 90% of drivers immediately increase their speeds to 100+mph on downtown city streets (i.e. people over reacting citing nightmare scenarios that pull at emotions rather than logic in a bid to control what other people can/can't do)
I think that you forgot to read the whole post, especially that part about people "appealing to emotion rather than logic," or do you seriously intend to claim that people won't make those arguments (wrong or right) whenever such a proposal is tabled?
