It's impossible to have a completely safe following distance. Some off-road hazard can inject itself onto the road without notice. All vehicles would be creeping along the freeway if they wanted perfect safety from such events.
So we can only trust in probability and do the best we can. Robot or human, same issue.
- narag 3y ago"Safe" is a simplification, but some practices are obviously wrong, like less than the length of two vehicles at 120 kmH. Some off-road hazard can inject itself onto the road without notice. All vehicles would be creeping along the freeway if they wanted perfect safety from such events. That's a tricky reasoning line. Safe distance is not intended for those cases. The point is that, given a colision, it won't be propagated. About congestion, it doesn't seem a problem if you can drive fast enough to make an issue of keeping the distance. Bottlenecks come mostly from exits.
