I've experienced this many times over the last 15 years or so. I'll pull into my driveway and try to remember what route I took home. It used to upset me very much until I tuned into a local talk radio station one day and they were discussing this very thing. I think our minds just go into some auto pilot mode. Anyway, lots of people were calling in who had experienced the exact same thing. Hope this eases your mind.
Thats the best idea it is probably something simple especially as you are so young , perhaps you are a thinker and day dream a lot and were thinking instead if concentrating on your driving, now you are more aware you will sort it out Good luck
HI margypops thank you for your comments. I am not on any medication, and not really under any kind of stress either and i sleep well at night, in fact i can sleep any where. my jurney from my home to my work is only about 30 minutes so i am not on the road for a long time. i will go and get it checked out though it might just be a lack of concentration or something simple like that. either way i need to get it sorted because i am worried that i might cause a crash or hit some body. i will keep you updated and let you know how i get on.
Thanks again.
Tell us more about your life , are you taking any Meds as ythey can have short term memory ,affects, have you had a lot of stress as I know that can make you forgetful.I have also heard that people who drive a lot and commute find they can get almsot mesmerised by the driving and have to pul;l over. Are you sleeping okay as Fatigue could affect you? If you are concerned and as you have your daughter and are driving perhaps you should go for a check up as a precaution, Let us know how it goes.
