Cops drive ~100 miles a day on average and maybe max of ~200 miles if you're far off in rural area.
If you're driving an electric car, then you're basically starting your daily drive with 300-400 miles of range with 90% charge. And cops in city do avg driving speed of ~30mph for most of the day when driving, and many times, they're just idling for hours at end waiting. If you're a police department, you're saving ~$100/car per day on gas alone. So if the car is being utilized daily, thats a saving of ~$37K per year, on one police shift. If the car is being utilized with 2 shifts, thats $75K in gas savings per year. Charging at police station with level 2 only takes like 2-3 hours. Charging at dedicated L3 charger takes like 30 minutes, basically cops eating lunch in their car and charging.
