E-bikes still have a massive carbon footprint compared to regular bicycles,

The comparison is not between regular bikes and e bikes but between e bikes and cars. E bikes win this.

Either way, a car, even if its an EV, will be the better pick for every situation I stated above.

A 3000€ gaming machine will be better in any task than a 500€ office pc. But as long as the office pc is sufficient, why spend the extra money?

Don't let perfect be the enemy of good. If you'd prefer to use a purely pedel bike go right ahead, but I find having a boost for heavy loads and hills makes biking preferable in situations it otherwise wouldn't be. My battery is a 0.8kwh battery, which is more or less 15 iPhone batteries strapped together. My car is a 65kwh battery, literally 100x bigger for only 10x the range. While hard to find info, my understanding is my car is one of the more efficient ones out there too.

battery efficiency

Never comes into play, my bike has a 40km range with no load and no pedaling so typically even in winter the battery is far bigger than most trips I would take. There is also a longer range option (I think 100km) and you can quick swap the batteries if you really wanted to marathon. I do take the battery inside in winter as starting it warm does help it alot. I probably would be more hesitant to take heavy things in particular if I didn't have the battery.

Well no, if you look at my comment I do own a car (bolt euv). I literally couldnt take the fridge in the car, i had to go home and grab my bike which could carry it. I use my bike because my city has good infrastructure that makes it quicker than driving. No need to hunt for parking, and the exercise is nice. Being able to use it while lightly intoxicated is also a plus.

Ebikes actually have a lower carbon footprint compared to regular bikes, because they go more kilometers in their lifespan.

Keep coping loser. Many of us will be trying to actually fix the mess.

Lifecycle emissions of ebiking can be a couple times lower unless you eat very green. Its been regularly over 100F here and I wish it was a desert so I didn't have to also deal with humidity: I've ridden in thunderstorms and think its nicer than riding the middle of the sunny summer days. Either way, still better than driving in traffic. For moving large things, a car is not any better. And driving around a moving van every day would be a huge waste when you can just use them when you need them and drive a much better vehicle (a bike) when you don't.

You can make more than 100 ebike batteries with the same amount of lithium as one electric car battery.

Twice of something that isn't very big in the first place.
