They recommend estimating 4.5 seconds of stopping distance. But that’s very conservative and probably not realistic.

- throw10920 3y agoThat's ridiculous. There's nothing "unrealistic" about 4.5 seconds of stopping distance - how could there be, are you thinking that the highways physically wouldn't fit all the cars spaced at that length?
- bumby 3y agoIt's unrealistic if you expect the existing infrastructure to meet both that requirement, the capacity requirements, and the time requirements of people travelling. In the real-world, there are tradeoffs. People who don't understand that tend to have superficial understandings of the problem because their mental models show little nuance.
