People with families strongly prefer crossover models and they've mostly pushed sedans out of the market. It would stand that an electric crossover would outsell a 4 door sedan.
Wouldn’t families strongly prefer a larger car period? Is the Y really that much bigger that it’d convert families who are holding out on a 3 due to size? I haven’t seen anything to suggest as much, and both the 3 and Y are def less roomy than other (albeit non electric) cars that families go for.
