When there are more cars parked on the drive delivery drivers do have to reverse back up the driveway, in the past we've had grass churned up or plants damaged where they've not been able to stay on the track. On one occasion a driver left most of their wingmirror on the drive. Shocking how poor some of these delivery drivers are at manoeuvring. Given that I try and park so that there is plenty of space to turn so that drivers can spin around and not face a long reverse up a hill and around a bend.
With only the camper and range rover on the drive there is space to spin around a much bigger van if you are not a complete idiot. Why would he choose to turn left onto grass when there is hardstanding on his right?
