There is a lot of air up there. I fly drones in Australia (https://serio.com.au/ https://serio.com.au/) and it's easy to stay well out of the way of large aircraft (don't launch anywhere near airports, and restrict your maximum altitude) and helicopters (you can hear them from a long way away). DJI's software enforces a survey with local regulations before you can fly. The default settings are all very restrictive too. The authority here provides an app that quickly indicates the flight rules in a particular location - airports and approach paths, non-controlled aerodromes, etc. It's quick enough that it's easy to check as part of your setup procedure. The riskier situations I think are cropdusters (fly very low and launch from rarely used airfields) or sightseeing planes/choppers (operating close to the ground despite launching from a fair distance away). I often fly at this location (https://serio.com.au/media/20180171.jpg https://serio.com.au/media/20180171.jpg) and on weekends there can be vintage sightseeing planes coming down the beach in that bay, definitely below the 120m (400') drone limit.
