I’ll start. Stopping distance.
My commute is 95 miles one way to work, so I see a lot of the highway, in the rural part of the US. This means traveling at 70+ mph (112km/h) for almost the entirety of the drive. The amount of other drivers on the road who follow behind someone else with less than a car’s length in front of them because they want to go 20+ over the speed limit is ridiculous. The only time you ever follow someone that close is if you have complete and absolute trust in them, and also understand that it may not even be enough.
For a daily drive, you likely need 2-3 car lengths between you at minimum depending on your speed to accurately avoid hitting the brakes. This doesn’t even take into account the lack of understanding of engine braking…
What concepts do you all think of when it comes to driving that you feel are not well understood by the public at large?
Roundabouts. Why don’t people understand these? You wait for the car already in the circle to go, then you can go.
Though as someone who lives in the UK with LOTS of roundabouts, I wish people would be better at using their indicators to signal their intentions on roundabouts… so much wasted time waiting for a car coming from the right only to have them turn off before they get to me without indicating. Or even worse indicating left as if exiting the roundabout then carrying on round 😬
And the part where you give way to people on the left or right (depending on country).
In the US with how infrequent roundabouts are, there is one in a popular city near me and it’s always a mess, right at town square.
