Summary
Quebec has passed a law banning the sale of gas-powered vehicles by 2035 to reduce greenhouse gas emissions.
Starting in 2034, advertising gas-powered vehicles of the 2035 model year or later will be prohibited, and by the end of 2035, selling or leasing new gas-powered vehicles will be banned.
Exceptions include emergency, rental, and off-road vehicles, while used gas-powered cars can still be resold and driven.
Quebec aims for 2 million EVs on its roads by 2030, though challenges remain as EV rebates phase out starting in 2025.
Most probably, that user was concerned with the already known issue with cold being capable of drainning batteries but as you so well stated the technology is advancing in leaps and bounds and the momentum in increasing so, given time, even that concern may very well be a soon forgotten issue.
But even if not, I’ll risk keeping the batteries a safe temperature could be solved by adding insulation to the space used to store the battery in the vehicle. In warm(er) weather, vents could allow for excessive heat to exhaust.
Just a thought.
Solid state batteries solve the temperature problem and are already being practically applied for cars. The History > 2020-Present section of this article shows well how much global interest lies is in these.
