Well, the Tesla Model X already seats 7, plus storage space, has over 300 miles of range (which I guarantee you is larger than the bladder capacity of the smallest of those 7 passengers). recharges faster than you can feed the whole family (which you also probably do a few times on your trip). and has a battery warranty of 8 years and unlimited millage.
So basically, your arguments are either already addressed, or artificially created.
How about price? Model X starts at something like $75k and the Malibu hybrid he mentions starts around $30k.
