I don’t know how stupid YouTube devs would have to be to:

• Tie the delay that was supposed to fight AdBlock to user-agent (changing it to chrome fixes the issue)

• Ignore Youtube Premium users that pay for ad-free experience

For those reasons I think it’s pretty safe to say that this goes beyond stupidity and into malice territory.

“Engine and technology advancements” can also be applied to smaller cars so that doesn’t really move the needle anywhere.

I think it’s quite obvious that unless you discover how to break the laws of physics, the smaller car will be always more efficient due to better aerodynamics and lower weight.
