Reckless drivers.

Why do your drivers drive so recklessly? CY 416932 today at 12:00 in Rondebosch where it is a right hand turn makes a left turn nearly taking me out in my lane. Then in a 60 zone he was cutting in and out of the lanes and even taking corners and never uses his indicators. Even on the N@ afterwards he was still changing sometimes even 2 lanes i.e.. right across 3 lanes without indicating. He is really putting other people at risk.
