The first reason is that you are trusting that person with your life. My mom got into a bad accident this way. Someone waived her in and although they were trying to be helpful, they must have missed the vehicle heading her way and she drove right into a lane where another car spun her car completely around. Thankfully, she was wearing her seatbelt and only came away from it with some bruising. For this reason, it is best just to wait until you have a clear view of the road. There is another reason to not trust someone to waive you in-scammers.
Yes, they are out there! There are organized insurance crime rings and they are always looking for ways to collect your insurance money. Take the accident described above but say the person who waived my mom in was organizing a scam with the person who hit my mom. This is one of many car accident scams. So, next time you need to get into that lane, it is best to just wait until you can get a clear view of the road instead of trusting a good samaritan trying to waive you in.
