a novel solution, well done.
I want to go one step further, have an external connector in the front grill, that I can plug into, even better if I can modify the alphard logo to flip up, use a standard EV charging socket.
Then, you could sneakily park in EV spots and plug in ( obviously it would not actually be a live connection from the EV charger to your car). have some animated red light near the charging socket to fool the casual observer that you are actually charging.
A sneaky EV sticker on the back (Easily purchasable) and bobs your uncle, an actual external socket you can use to jumpstart or trickle charge, plus the ability to use larger parking spots if not scrutinised too closely!!!!!
WHat do you think!!
