I have had no proper instructor, learned from my boyfriend while HE drives and I have driven myself for about a year I just feel I have picked up alot of bad habits from him. I switch lanes at the same time that I put my blinker. My boyfriend says realistically no one will let you in the lane if you signal ahead of time. I also go above 5 to 10 more than speed limit. Should I get an instructor for a few hours and see what he thinks?
