I think there are a lot of bad parkers out there. It took me almost two years after I passed my test to feel comfortable reverse parking into a space. I still give myself a little pat on the back if I parallel park between two cars in one go. But there are people who park crazy and literally don’t care. There are so many memes out there of crappy parking so I won’t elaborate too much.
You know the sort, people in huge cars straddling two spaces. People who look like they’ve parked with their eyes closed. Those who park about 20 feet away from the kerb. People in expensive cars parking so close, your climbing out the passenger side because you know you can’t afford to pay for any damage you cause. Please, go take another few lessons. (Btw, that pic is of my parking, I know. What a douche!)
