Bikes are a local thing. If the weather is too hot, or cold, or wet, or snowy, you're out of luck.
Cars appeal nationwide. They'll get you hundreds of miles, comfortably, between remote destinations that aren't served by public transport or airports.
Or, they'll help you get groceries for the whole family.
If you think your area would be better off if tax breaks went to e-bikes, write your city and state governments. Depending on where you live, they're already taking upwards of 10% or more of your income, plus taxing the goods you buy and the land you live on.
