I had to buy my first car for work, after passing my test 20 years previously and hardly driving at all afterwards. It was delivered on the Saturday and I was driving it to work on Monday.

I left early doors to avoid the traffic and same coming back before it got busy.
The first few days were interesting but it built my confidence up.
One thing I noticed was it was much easier picking lanes when it’s quiet. On a busy road the road markings obviously get hidden by cars, so it’s almost like driving a different route
Driving is easy, take your time and don’t be rushed (but don’t sit for 10minutes at a junction backing everyone up ) - it’s keeping an eye out for idiots around you that’s the biggest problem IMO
