We need a permit system for CA freeways.
This morning, on my way to work, I decided to be nice, my first mistake, and let a couple of cars merge in easily from the entrance ramp. Meaning I left them both lots of free space, about 14 to 18 car lengths.
The first car merged in easily, taking about 4 car lengths to do so. The 2nd blew through all 10 of the remaining car lengths and started to cut me off by merging at my space.
When you merge, you are to accelerate into the traffic, not cause problems by slowing into traffic.
This is why I do not believe that everyone should have freeway privileges. Some people are just too stupid to have them.
