Flying car
I like the idea of using a hybrid Tyre Rotor for a flying car.
The hub could also act as an electric motor.
The tyre spokes also act as the rotors, which retract from the rim to allow for spinning.
An arm comes out to hold the wheel, while the axle retracts to allow for the wheel to be turned 90 degrees by the arm, the axle then pops back out and re attaches back to the hub, the arm holds the tyre and outer rim, while the spokes retract from the rim to act as the rotors driven by the electric motor in the hub.
While the car is stopped
1 4 hydraulic pins come down then lift the car slightly off the ground
2 Two arms comes out to hold each tyre
3 axle then retracts
4 arm then flips tyre 90 degrees
5 Axle then reattaches back to the hub
6 spokes retract from rim
7 spokes then spin and start lifting the car upwards
8 hydraulic pins retract
9 an option would be to have winglets to slid out for gliding
10 tail for stability while gliding.
11 small jets at the rear for fast short duration acceleration
12 both car and quad copter could have self driving modes.
