Ecars and bikes might be perfect for running around town, but cost and battery life are the current down sides. A tesla model 3 is what $40k usd? Plus being 500-1000lbs hevier than a corolla it'll go through tires a little faster. The wife's fiesta was $17k and averages 31mpg around town. It'll take a long time to use enough fuel to even out the purchase cost.
Now e motorcycles are a little more even to start. $20k for a zero, lots of bikes outside the starter bike range are getting close to that. If you only ride around town or commute most people would be able to charge at home and never worry about range. Longer trips are where the IC bikes have an advantage. For example my tiger, I put an 8 gallon tank on it and get over 300 miles highway between gas stops, and filling it up takes under 10 minutes.
Now as costs come down and batteries improve the advantages IC has will start to go away. But so far the batteries aren't there yet. Because the batteries dictate range and charge time.
