Fair points, but it think my point is this Cost to drive (.50/mile) = $40x2 (round trip)= $80 @4hrs General aviation 20min+45min (Cessna 172) + 20min= 1hr 25m

Fair points, but it think my point is this Cost to drive (.50/mile) = $40x2 (round trip)= $80 @4hrs General aviation 20min+45min (Cessna 172) + 20min= 1hr 25min x2 is 2hr 50 min (let’s call it 3hr) 1.5 hrs flying time @$300hr (let’s exclude cost of ground transport) means $450. So $270 to save an hour If vtol saves another 2.5hrs for $270 and has the same cost profile, Than that’s great, you’re still spending >$100hr on time savings (and this optimistic, because I think most uses cases have lower ratio of airport travel time to flight time, you would then need to value your time at >$285k a year (pre tax @30% and 2000 hrs a year), which is not that huge a group of people
