Also designated smaller roads for bicycles and other small personal transport (maybe allow the rent-a-scooter businesses too especially if the city is, you know, too diverse or the crime rates are high for other reasons)
Also a speed limit that won't be ever higher than manual bicycle maximum speed achievable by a trained person, just so that visiting bikefags and the like wouldn't kill anyone, plus the city is to be planned in a way where you wouldn't really need to hurry anyway
For the especially rich and need and needful for speed - public helicopter rides
