Intelligent people leave a space of about two cars ahead of them on the freeway.

Stupid people think that space must be for them.

Two car lengths isn't even remotely enough space if you're traveling at high speeds.

Yeah, I follow the 3 second rule and try to keep 3 seconds of travel distance between me and the car in front of me

This is it. Absolute minimum two seconds in perfect conditions, four if it's raining/dark/whatever.

It depends.

On a well developed well maintained "freeway" with multiple lanes, shoulders for break downs, gentle curves, et cetera it's common. 3 car lengths is more common here I think.

That said, on a "highway" (interstate?) without everything listed above I aim for 2 seconds, which is about 60 metres at highway speed.

Intelligent people leave a whole fucking lot more than just two car lengths.

[–] greyw0lv@lemmy.ml 3 points 19 hours ago

Back when i drove. I was taught 3 car lengths, or 3 seconds. Whichever is greater.

I think they're saying 2 car lengths when in heavy traffic going 20 mph. I hope...
