Demonstration of car-plane concept

Demonstration of car-plane concept
The objective is to design a functional, plausible, self contained car-plane able to takeoff and land from highway stretches.
Concept is based on supposition that empty weight can be brought down to 700lb by any means necessary. rotation speeds: 120kt wing up, 85kt wing down. Wingspan with wing down: 16ft. landing ground roll wing down, slowflighting in at 65kts: 1200ft.
Note: the 4x50hp props are meant to simulate a 200hp generator providing power to 4 electric motors. Everything using existing technology to create something 80% functional as both car and plane. 0-60 in 6 seconds, 40 gallon tank provides 600 mile range at 12000ft/230mph (10gph@0.5sfc). Absolutely plausible design, only barriers are regulations, cost and lack of customers.
