To be fair, any vehicle can get stuck in the snow. Even one with high ground clearance and four wheel drive. The person in this vehicle needs to get out, grab a shovel and remove the snow.
However, electric vehicles or EV's are very heavy, and many EV's have a very low ground clearance that isn't adjustable. Build up of snow on the side of the road would cause a problem for many of them. For example, the Tesla Cybertruck weighs between 6600 and 6900 pounds. A gas powered Ford F150 weighs between 4000 and 5700 pounds. Combine the weight with the initial cost, battery charge time and affects of cold weather on EV batteries, makes a gas powered vehicle the better choice.
