I agree with this completely . The first test I booked ( I wasn’t ready for at all just over confident) I had only practiced with a parent next to me . I failed miserably
I then booked proper lessons with an instructor for about 6 months and practiced with my parents as I went along . I learnt so much more doing it properly and honestly I don’t blame the driving examiner for stopping my test half way through the first time . Second time test , I passed and felt so much more confident with it . I was 17 when I thought I could “wing it” and oh how little I knew lmao . I do think it should be regulated . I could have caused an accident by being a cocky teenager
