I think I fall under the category of "serious commuter" as I commute from Aptos to Hayward three or four times a week, (134.4 mile rd trip).
I was doing that in our ford explorer (24.9mpg) and it was running me like 15 bucks a day to go to work, which was not sustainable obviously. In Feb I picked up a 2015 Zero DS 9.4 that has racked up 3800mi since then. It saves more on gas than its monthly payment and insurance cost, and when the tires go in another few thousand miles, I will still be well in the positive. It did have one problem, and that was the onboard charger, It worked, but only intermittently, but it was an easy fix.
Also, you can flog the crap out of an electric motorcycle, and nobody even turns and looks, they are the ultimate hoon machine, and the DS is IMHO the best of them. (Slightly taller suspension makes for more lean without bottoming on corners, and they LOVE stairs)
BTW, Pilot road 4s rock, and they come in the DS's stock wheel size.
