My youngest is going through virtual drivers ed and as the parents we now need to do the on road training which we did anyway but now we need to keep track of the hours.
First day of virtual drivers ed the teacher told my daughter she should purchase signs for the car so she did ... I guess it's something new but is a good thing so she purchases these signs (see link below) and none of them stick to our cars ...
They are magnetic, we tested it with our extra freezer and they stick ... why not on the 540 or Q7 ...
BTW my wife tried it out on the Cayman and it stuck .. yes she is still alive because I wanted to kill her for trying it out
