I have not had any normal car try to block me in this way. However, an 18 wheeler tried to slow me down one day...would even swerve into my lane each time I attempted to pass. Eventually I said **** it and went pass him. Got the truck number and reported him. I admit that I speed however it is not his job to enforce the speed limit.
