Driving need practice and calm.
When I was driving with someone I always made mistakes, because of someone voices beside or behind me like “too slow”, “too fast”, “look out”, “on the left”, “You missed it”…
I started to drive confident and superb when I finally had my DL and I drove without anyone.
So a lot of patience for you all and don’t break down after mistakes.
Fe, I needed to drove into someone while parking to finally “feel cars” 
Now I can drive anything - vans, bus, etc
