> Why are they using garbage trucks to plow snow?
Perhaps because it's easy to add a connector plate and a bit of hydraulic in front of a truck and they already have them for garbage, they regularly run the on roads and their driver knowing where garbage containers are avoid some classic (at least here in UE) where the snowplowers push/launch snow everywhere not caring about anything else then keep the road clear... In a city handling snow it's even harder than in the countryside...
> But it's silly to decide to have an all-fuel fleet of garbage trucks just because they can't also be used as snowplows a few days per year that you need them.
Keeping up two fleet is not that cheap either: trucks/wheeled vehicles need to run regularly to keep their wheel well round and balanced, ICEs need to run regularly to keep the engine well lubed, starter and service batteries need to be kept charged, vehicles need to be parked somewhere (two fleets, twice the place), for ICEs you need to keep the fuel infra ready, and the amount of fuel it's not so little and so on.
IMVHO as an EV owner I doubt ALL trucks can be electric so far, simply range, charge time, battery weight are still below a practical usability levels...
