I've been driving for years and I don't brake check tailgaters, but I don't accelerate either. The only times someone has rear ended me was when I stopped at a traffic light and they weren't paying attention, so as much as people try to intimidate you, it's rare they will actually hit if you are driving in a reasonable manner, so I think it's actually fairly safe. I would like to reduce peoples stress though and I feel like indicating that your vehicle is in some sort of automated mode would likely reduce other drivers stress and generally be beneficial.
