This seems like a no brainer to me, but absolutely. Cuts emissions, saves you tons of money on fuel, makes you healthier. Unless you are hauling something, there's usually no reason you need to drive 4 miles when it can be biked instead.
I rarely drive anyways, but did the math and I'm saving around $800+ in Costco fuel alone. This would be significantly more expensive if I bought gas anywhere else. That's enough to buy a new ebike battery every year and still have savings left over for gas money when you actually do need to drive somewhere without public transit.
The end result is that I'm basically getting an ebike for free in gas savings alone after two years of use, lmao. The vaguely sickening part is that even pedaling around 15 mph, I still manage to arrive at my destination only 10 minutes slower than driving, which is insane. At certain times of the night, even in suboptimal conditions (eg, construction on the bike lanes), I've actually made it home by bike in the same amount of time it takes to drive through dozens of traffic lights, traffic, stop signs, etc. And charging my bike costs pennies.
