I took your estimate of 0.24 profit from cars and added another 0.26 profit from batteries and charging stations. Electric batteries (About $8000 each?, if I recall others posting)(charging stations I dont know),
So 0.24 your estimate for cars plus my estimate for batteries etc 0.26= 0.50 PROFIT FOR THE ALL ENTERPRISE.
MULTIPLY THIS BY ANY P/E YOU WANT, gives the future PPS.
