Ah, I should have been more clear. In my locale, those roads also tend to have fairly high traffic density, going at a fairly high speed, especially during commuting time. Plus they carry most of the truck traffic.

Under those conditions, following distances are close enough that a driver can't stop their car or make an evasive maneuver without causing a pile-up. That's what I meant when I said that the drivers aren't controlling their cars. I just consider those conditions to be dangerous. Granted, each of us has our own comfort zone.

I would have no problem under the conditions that you describe.
