Simple physics demands that this use less energy.
E = mv^2/2.
Say cars are 10x the weight and drive 2x the speed of an electric bike. That’s 40x energy.
Additionally, bikes are more likely to have less erratic go/stop behavior, so even more efficient. For example, I’m much more careful to coast on a bike than a car because it’s my energy.
So look at the drug war, war on terrorism, money laundering sanctions, international tax evasion measures. The US and EU basically force the world to comply.
Imagine the EU and US are fully on board and say Australia decides no. What would happen to the Australian economy if they suddenly were barred from trading the dollar and euro. Australia is a big country and would be on the US/EU side. Imagine if Mexico or Croatia tried that. No chance.
Extreme? We did that to Russia during the Ukraine invasion.
This isn’t difficult. They just don’t care enough.
