There are no EVs that would currently get to your son’s and back on a single charge, but there are some that will do the trip one-way between top ups.

The Tesla Model 3 Long Range, for example, has a 374-mile range. Be wary, though, electric cars chew through their battery quickly as cruising speeds because they don’t get the regenerative effects of their brakes when there’s no stop start traffic. At a steady 70mph, getting to your son’s may be tight.

On the upside, Tesla’s Supercharger network is excellent – giving you a quick, easy and reliable way to charge the car.

It’s head and shoulders above the open networks used by other EVs which are often over subscribed, broken and require you to sign up to a myriad of different apps and subscriptions just to use them, although the Government has recently announced plans to address these issues.

Putting your heated seats on is one of the most efficient ways of staying warm in an electric car – much more efficient than using the heater. I would have thought it would lower your range by no more than say 30 miles, but that's an educated guess.

It is hard to say exactly what effect heated seats would have on range because there are so many other factors to consider like the ambient temperature, tyre pressures, whether you're driving in the day or night, the speed you're driving at and more.
