Compared to ICE vehicles, EVs are expensive and heavy

Expensive maybe, IMHO not really, at least in China. Heavy .. this doesn't sound fair. Are you comparing a cherry-picked, heavy, full battery back EV with an empty tank ICE? Noting the EV has far more torque, and that the same tech is used in UAVs and in a ground vehicle you can arguably move the weight around (lower it) easier in an EV, this casual observer (not a car person) would expect superior mass distribution and lower overall weight (certainly vs torque).

500kg solar EV: https://www.unsw.edu.au/newsroom/news/2022/06/sunswift-7--dr... ... compare Toyota Corolla: 1314kg + 50kg fuel / Toyota Camry: 1360kg + 70kg fuel / Tesla Model 3: 1611kg / Toyota RAV4 average: 1634kg + 55kg fuel / Tesla Model S: 2107kg / Tesla Model X: 2458kg / Your cherry-picked example of an F-150 Lightning: 2948kg / Chevrolet Silverado 1500: 3311kg + 105kg fuel / way more heavier ICE cars follow...

Another potential consideration is that the EV is far better placed to use recovered power from braking, so a small amount of additional mass will have less efficiency impact than in a comparable ICE.

Vehicle weight also affects how much wear the roadways experience. I'm not sure "A Corolla weighs less than a truck" is relevant here, especially considering that the F-150 is the most popular vehicle in the US by sales number. Comparing things to the market leader is generally a useful metric.
Heavy trucks damage roads much more than cars. It depends on the weight but it’s exponential. The weight difference between an EV and an ICE of the same category is not a big concern to have in terms of road damage.
