Electric cars can't cut UK carbon emissions while only the wealthy can afford to own one

"Then the challenge of clearing roads of EVs with flat batteries. Not quite as simple as a few jerry cans of fuel and some jump starts."

"

Unless somebody started their journey with a minimum charge, draining the battery and having to be towed from the motorway isn't going to be an issue. Most EVs have heated seats that don't take a tremendous amount of power. You also aren't sitting in the car with an idling petrol/diesel engine. If we take 60kWh as a modern average EV battery capacity and it's at 50% charge, then overestimate the seat heater power at 1kW (or 500W x two people in the car), that's still 30 hours before the battery is completely flat. Very slim chances of so much snow that it's 30 hours for crews to clear a lane to get vehicles off of the motorway and someplace where people can hole up in a hotel, restaurant, etc.

It's far more likely that people will have far more of a charge in their battery anyway and the seat heaters aren't so power hungry.
