I concur with Geoffry. On numerous occasions, I have been tailgated by modified vehicles and incensed by loud, retro-fit mufflers. I have also witnessed, again on numerous occasions, modified vehicles weaving in and out of traffic. It goes without saying that it is wreckless driving and it endangers others on the road as well. When I know my family and friends are on the road, it infuriates me and I thank the DRPS for looking out for everyone's safety.
