It is mostly me. But I have had several surgeries on my eyes that make driving at night a little challenging, so if we are out with the kids at night, I have her drive just for safety sake.
Overall my wife is, how do I put this without being critical, a very safe driver. She tends to do the speed limit or even lower, which doesn't work these days. You need to drive with the flow of traffic. She also defers to other drivers too many times instead of just taking the initiative and making a move. Every time she comes home from work she has some story about this person honked at her or flipped her off because she was driving so slow. I feel bad for her but I know a lot of it is because one time she was driving with our kids when they were little. She was approaching an intersection and had the green light, but out of the corner of her eye, she caught this van that was about to blow through the red light going the other way. She slammed on her brakes, ended up getting rear ended by another car, but probably saved their lives because that van just sped through that light. Even though this was probably 10 years ago, she reminds me of it every time I say anything about her driving. So it is hard to complain....
