“There’s something I’m not clear on. EVs have a huge, heavy battery - but they have no IC engine or radiator. Is the weight of an EV electric motor comparable to the weight of an IC engine and the associated components?”

Lithium Ion is, by far, the most efficient battery-based energy storage medium available for surface vehicles. But to have a decent range, it still takes a huge quantity of the batteries and thus a HUGE weight. I have no clue if their car parks will collapse, but if they do, they certainly weren’t built with much margin for heavier vehicles.

...GMC Hummer EV...The Edition 1 version, which has lots of batteries for additional driving range and power, weighs over 9,000 pounds. That’s roughly three times the weight of a Honda Civic.
...The Ford F-150 Lightning will weigh about 1,600 pounds more than a similar gas-powered F-150 truck.

1,600 additional pounds for a light-duty truck is significant.

I agree wholeheartedly that EV's are heavier than their ICE counterparts, largely from the battery.

However, I'm having trouble believing today's EV's are heavier than cars from the 1970's (as the article states the standard for car weights were when the parking decks were designed).
