Not much room in the garage on either side of the car

[Numo]

Years ago some cars had little antennae-like things that stuck out low from the side of the car to let you know when you were getting too close to the curb (they made a noise).

Could you somehow use this technique? If not on your cars, perhaps on your walls?

Also, could you cover the support pole with some dense foam padding so you can park as close as possible to it?
