You need a much faster ebike, so you cross paths with far fewer cars, and the ones you do, look at you in amazement. Plus there's the added bonus of catching one after doing something stupid like that. If someone pulled a stunt like those with me, they will receive damage from the chain I use to lock my bike and if they're lucky the damage will be only to the car. Luckily I haven't run across such idiots here in about 20k miles. The most I've gotten is a hoot and holler from a car full of teenagers trying to startle me, to which I just respond with an EV grin and blast away leaving them in the dust.
I take it back, you should move some place nicer AND get a much faster ebike.
On topic, I get right at a penny per mile of electric consumption on my crazy power ebike, and my lower power ebikes get about the same, because cruising speeds are similar. The price of gas here is about $5.50/gal. My ebikes save a couple thousand real dollars a year, but that's just the raw dollars. The time they save me is worth drastically more than that, and the convenience and fun are priceless. While the purchase of a 2 wheel gasser is hard to justify, an ebike is easy.
Before anyone starts trying to pick it apart bringing up battery costs etc, the only valid comparison in my case is on variable costs alone, gas vs electricity. I'm not amortizing the cost of my car, or insurance, registration, inspection, repairs, etc. Those are all sunk costs. On the other side, because I got deals and DIY'd my batteries, none of which are totally worn out, my batteries are worth locally nearly what I have invested in them. That's because lithium batts simply aren't available here. Plus I could easily sell my ebikes at a profit, including recovery of the cost of failures or those still in the project queue. That means there's nothing to amortize. It's all a moot point anyway. Ebiking and ebuilding is my hobby, and it's the cheapest hobby I've ever had before considering what I save on gas, so there's real $ savings there too, which is added to my real dollar savings electricity vs gas.
