I have been driving fulltime for 33 years, and I think it’s normal for a newer driving to have some anxiety or nervousness about driving, and it may help keep you on your toes. When you get complacent, or let your guard Down, you are more likely to run into problems. I drive like I have a 4 foot barrier around my vehicle, and try not to let anything get near my barrier. Just last week I had three kids on a bicycle turn into my path, and they never saw me. I had to use my horn, and stop my vehicle. Always be the best you can be.
