Where did you get that information? I’d like to see it for myself. Mind you, I have no doubt that methanol is unsafe to drink, but so is gasoline. I’d like to see an objective source of information that shows methanol to be more dangerous than gasoline.
Call your local poison center. Ask them about lethal dosages.
Average lethal dosage, ingestion or absorption, for your average 70kg adult:
Gasoline: 115-470mL
Methanol: 60-240mL
See the difference?
Another problem is that methanol fires are literally invisible. You cannot see them. Gasoline fires are blatantly obvious. For this reason, IndyCars switched to ethanol from methanol.
Also, here’s the source re: methanol poisoning: http://www.medicinejournal.co.uk/article/S1357-3039%2807%2900324-6/abstract
It’s also nasty because it’s even more readily absorbed into the skin than gasoline. You will need to wear protective gear to refuel a methanol car.
