I do think that there are some very judgmental nasty comments on this thread.
I only learnt to drive this year, I passed first time while 6 months pregnant and was really proud of myself. I bought a car a few weeks later and did my first journey post test round the godawful one way system in Croydon using Satnav, and it was like a baptism of fire. I had some mouthy twat shouting out his window at me because the road I was waiting to pull out on was bumper to bumper and nobody was letting me out (like its my poxy fault), and ever since then I've experienced so many other wanky male drivers getting right up my arse, beeping at me because I'm doing the speed limit and the like, I can only agree with one of the other posters who said she doesn't want to be part of that competition. I just want to drive safely as I was taught, not bomb around like a cock and the tossers in their BMWs and Mercs round here don't seem to like that.
Plus, my sister (who passed 5 years ago and drives for a living) came round and we did a little trip out to a garage and she was a complete arrogant git while in my car. It was all 'why do you do it like that?' and 'don't you do blahblah?' and then laughed hysterically when all her pissy comments made me nervous and I stalled. Oh and she also expressed shock when I said I wouldn't be driving an hour down the motorway to see her while heavily pg.
I'm still cross with her.
After several weeks of all the above I started to get very upset and nervous about driving, and tried to avoid it. Didn't help that I was in a serious crash years ago which left me with a buggered up left arm, and my good friend was killed in a motorbike crash only a week later. Bad things happen on the roads. I started to totally lose my nerve.
Then dh sat me down and gave me a pep talk, and the driving I've done since then has been a bit more confident.
That said, I'm 36+3 now and a bit too hormonal/ emotional for driving at this point. Plus, having never been on a motorway before I am nervous about doing journeys to see my family after the baby arrives, as they live an hour away.
As long as you're not a dangerous twat on the roads, or so scared that you make dangerous mistakes, you're fine as a driver, whether you're comfortable bombing along at 70mph or not. Everyone is different.
