1. people that think you are to close behind and slam on their brake, its one of the most dangerous things that happens
Maybe, that if this happens to you often, you need to review your following distances.
Your definition of a safe distance may not be the same as what someone else finds comfortable.
I have driven over hundreds of thousands of miles, across England, Scotland, Wales, and Europe, and I have NEVER had this happen to me, EVER. The reason? I always leave a v large gap between me and the car in front (much more than a few seconds).
When I'm holding back like this, I see all the cars in the distance sat bumper to bumper, doing 70mph. If the front one were to brake hard, then they would all be like dominos. whereas I would stop at leisure.
When holding this far back, and looking at them all driving so close - to quote yourself... THEY are the "idiots"
You may say my following distances are excessive, but, I'm never at risk of rear ending anything, I know for sure I'm never making anyone uncomfortable (I'm not the type to want to do that)... and... oh look... I got somewhere 30 seconds slower than the tailgaiters in front... big deal!
I COMPLETELY agree, some people's dawdling habits are a danger and people who are so stupidly slow are a liability...
However, the people dawdling compared to the people tailgaiting is extremely low
The one thing traffic cops need to focus on the most is tailgaiting.
It's by far the most dangerous, and most selfish activity that happens all the time on todays roads.
