While I understand that some of these things can be a bit too much, duct tape use will never grow old for me, even if it`s not for taping something into place.
For example, in this video, you can use it to mark where your seat was before someone decided to move it forwards or backwards, and you can adjust it accordingly after they`re done seating there. Also, another neat trick is using a paperclip to hold your sunglasses firmly while you`re driving – just put your glasses in the clip and clip them to your overhead sun visor.
They`ll stay there and most importantly you won`t have to look for them all over the car before you get out, and you know you`ve done that at least a few times.
Besides duct tape use, you can also utilize your own body – if you want to unlock your car from afar, point the remote against your chin, which will somehow help extend its range. Also, if you want to shine up your headlights, clean them with some toothpaste. If you want to create a car cinema in the back, take a clear plastic bag, put two holes in it and put the headrest rods through those holes.
Put a tablet in the bag and presto, you have your car cinema. Finally, if you want to stop a chipped part of your car to stop chipping, put some nail polish on it – as soon as it dries up, it will prevent the exterior from chipping any further.
Finally, here is a great animation to show you how to park between two cars!
