> Norway is already at ~80% EVs for new car sales. There are gas stations that are ripping up their pumps for fast chargers.

What do you do about the snow plows, garbage trucks, ambulances, police cars, buses, etc....vehicles that are currently being used for several hours a day and can't have any downtime??

Speciality vehicles will probably be the last ones to be electrified. I've not yet seen an electric snow plow, or even an ambulance.

The city busses charge over night, and some (I believe) in the lull between morning and evening rush hours. High traffic routes can charge while running(!) using overhead wires (city used to have old trolley buses). See [1]. They'll connect and disconnect to the wired infrastructure on parts of their route. At 3:14 in [1] you'll see the moment of disconnect. At 4:20 it reconnects. These busses can run continuously.

Taxis in the city are 50/50 electric and hybrid (prius) I would guess, just based on what I see on the streets. By law they have to all be electric by october 2025 in this county. Taxis have fast chargers next to their stands.

There are electric excavators and the like for inner city construction. Apparently some can run for up to 6h using only onboard battery. They usually drop some huge containers with charge ports near the work sites, which I assume extend this run time (+slow charge from the grid). You often see them connected with huge cables to these containers during static work.

Garbage trucks where I live are a mix of diesel and electrics. Majority is still diesel. Afaik the electrics run for a full shift. They're trying hard to get rid of garbage trucks where possible though, using underground pipes. You swipe an RFID at a "terminal", it opens, you dump in your garbage, vacuum pulls it to the incinerator facility, it gets burned, water gets heated, and then pushed back to homes as district heating. Obviously won't work for suburbia or rural communities.
