Any help?
I was driving back home and some dick head driver was trying to pass me up and the car infront of me. So I slowed down and let that guy pass me, then I guess he realizes that the guy in front of us wasn’t going as fast so he tries to pass him up(mind you I’m still behind the crazy duck head driver but like a car space away). He doesn’t pass him up but drives to the left shoulder lane near the cement side(fast lane) and as he went on that lane, something flew up and hit my right side cover mirror. I didn’t have a chance to check right away until I got home and saw this! -.-
Any advice before I go to my car dealership and get a quote. Ps, looking for a dash camera that works very well and last pretty long.
