You seem to be complaining because you're deciding to park directly under the stucco overhang of your garage. You could either park inside your garage, or a few feet farther away. You're deciding to do neither and park in a place that doesn't allow full clearance for your rear hatch to open.I back my car into our driveway, so that the power cord will reach. I cannot pull it in forward, because my charger, which is in the garage, won't reach.
Once backed in... there is a stucco overhang which, if I were to open my trunk fully, the truck would smack into it and it would probably damage the paint.
Your situation doesn't match everyone elses situation! I can spend money to extend the power cord, but honestly, I don't feel like spending the money just so I can park a few feet father from my garage door. I can *hope* nobody accidentally opens the trunk while under the overhead, but I again don't want to hope... accidents happen.
As for "not knowing any cars that use GPS to determine what height is safe"... the new Chevy Corvette uses GPS so that when a driver raises up their car, to avoid speed bumps, or to manage a steep driveway... the car will automatically raise the next time the car is in that same location. Chevy doesn't make their customer constantly raise and lower their car every time the approach that same location.
Why did Tesla add the feature to restrict how high your trunk can open? According to Kairide... everyone should simply park somewhere else! Garage ceiling in too low to open your trunk? Hey.. park outside of your garage!
You don't want to spend the money on a longer cord, which would be cheaper than repairing the rear hatch and your stucco overhang.
Your examples of cars using GPS are for adjusting the ride height, not the height the rear hatch opens. My Model S has adjustable suspension based on GPS, but it does not adjust the rear hatch based on coordinates. Also the Y has coil suspension, you can't just raise and lower a coil suspension via the touch of a button.
Tesla and other car manufacturers make built in memory for their rear hatches so people don't bash them in to low overhangs. How would the car know that the GPS location you're at has enough clearance for the hatch to open completely? Yes, the solution would be sensors, not GPS.
Yes, that's why you set the hatch at a level where it won't hit the overhang. You just need to decide what's more important, not hitting the overhang where you park daily or having to manually push the hatch open further when necessary.Overhangs are hard to avoid in parking garages.
