I haven't yet used the Tesla AutoPark, but I beleive that it relies on other car parked to be able to localise a paking spot using proximity sensors.
In an other way, the 2018 Leaf's system uses cameras and can park automatically without any cars nearby.
A combination of both systems would be interesting.
Note: Reading the above Smart Summon tweet from Elon Musk, it seems that this is what will be coming in the future.
