Yeah, those tie downs are not meant to hold much more than a few grocery bags. Not a scooter, wheelchair, etc. Your lucky the thing didn't fly loose and take your heads off. Could have been deadly in a bad accident.
Each one of my 5 vehicles has different spacing, size, etc. brake and gas pedals. I can adjust to them in about 5 minutes of driving. Anyone can learn to adapt.
I use rainex on all my vehicles. Twice a year. That stuff is great. Much easier application than a clay bar followed by a wax treatment. I have 5 vehicles. I chose the easier method...lol
