If your car is relatively new (couple decades) you don't need to warm it up, just drive easy for a couple minutes.

so your... warming it up?
The important part is that you're not prevented from driving when it's still cold.
What engineering innovation in the recent decades has enabled oil-lubricated internal combustion engines to not require warming up?
Much tighter electronic control of fuel, ignition and even cooling system combined with tighter tolerances and modern oil formulations. Wait for the cat to light off and the revs drop and then put it in gear and take it easy for the next couple of minutes of driving.
The main thing is that it takes a long time to hit operating temperature at idle. Of course it still requires warming up, but every knows the other poster meant sitting at idle, not driving easy for a couple minutes.
Getting rid of the internal combustion engine is the main one, but your point stands.
Planned obsolescence.
