Well the likelihood that this becomes popular and allowed on road (imagine if everyone was to flyoff in the middle of a traffic jam, you'd get air jam and probably planes hitting each other).

It's more likely to be used in remote areas like in the middle of Ecuador as Steve Saint the guy in the video was hinting at. Or like here in Canada, some areas in northern canada aren't accessible by road from the south, this could fly the required miles to reach the next road. (well it would have to be better insulated and fly a little faster considering the distances).
