By the end of the 19th century, 38% of American cars were electric. But early car batteries were expensive and inefficient, and the vehicles were twice the price of a gas-powered car. Enter the cheap Model T, and goodbye electric autos. Now that gas-powered cars have warmed the climate, can the market for electric cars heat up again? A TED-Ed video by Daniel Sperling and Gil Tal, narrated by Jack Cutmore-Scott, and animated by Lobster Studio.

Every evening, untold thousands of New Yorkers get dinner delivered by electric bike riders, but those vehicles are technically illegal. NYPD officers have been ticketing deliverymen even though lunch at NYPD HQ gets delivered by e-bikes.
The root problem is definition: when is a bike not a bike? When does a “power-assisted bike” become a moped, motorscooter, or motorcycle? And when do electric 2-wheeler riders need operator licenses? As with e-commerce, ridehail, Airbnb, and consumer drones, lawmakers are fighting a rearguard action after technology got well ahead of regulation, and it’s hitting New Yorkers where they eat. Ironically, NYC says it will let UPS make deliveries by ebike.
