Heh it doesn't have to be literally on one's own lawn, it could just be a little helipad per community. And my understanding is that the vast majority of private helipads don't have air traffic control - your hospital's roof doesn't have its own air traffic control. Pilots operate under "see and avoid" rules.

Use your imagination a little. So much status quo bias here.

Who would want to privately own a community helipad? Sounds like an insurance and liability nightmare.

This is an impressive enough achievement, but let's not kid ourselves this is going to revolutionaise suburban or semi-rural transport. Its maximum payload weight (450kg) barely covers 5 passengers with no baggage. It's for hopping from the country club to the golf course.
