There's a cure for that too. Move right, they'll go right past you.
You obviously don't live in California. Most of the time, you can't move right - it is too crowded with slower moving cars already. These jerks in their ego trucks have no place to go if they wanted to, and neither do I, yet they ride your *** like they have time to react if there is a panic stop, which happens a lot on congested roadways.
