Have you considered that there is more to expense than just filling vehicle, or for you, more to it than just 0-60?
Police departments are public institutions! They are financed from local taxes. Their budgets are ALWAYS tight, they are ALWAYS understaffed. Purchasing EV means also purchasing chargers which are expensive. It also means moving all your motor pool to know-how about EV’s. Or you can maintain them in local dealerships ($$$).
So, when PD makes decisions to drop out of EV, it is not only charging, BUT OVERALL cost of maintenance etc. on a budget that is super tight. Unless that PD gets huge grant+money for long term maintenance, bare bone pursuit Charger or Explorer are more cost effective option.
Yes, they don’t go 0-60 in 2,5875528 seconds, but they can go off the road and if they damage something, it won’t be $60,000 for battery.
