It is wrong (IMHO) that new drivers are allowed on motorways without any practical tuition and I think after passing the driving test, an hours lesson, given by a professional, should be compulsory.
The week after I passed my test I had a two hour motorway lesson.
We got on at our local junction, J10, and got off and back on again at every junction down to J1 then did the same in reverse.
My instructor, who had taught me to drive, kept up a running commentary the whole time:
"Look at this idiot"
"What does he think he's playing at?"
"At least when he's in front of you, you can see what he's up to"
"Good grief"
And so on and so on...
By the time we got back I was a nervous wreck 😳
