They could also put horses on a treadmill inside the car to fullfill the obligation, but, alas, that is probably not going to fly in the market.
I checked with Perplexity
A Tesla Model 3 cannot practically be powered by a horse, since the electrical power a horse can generate on a running wheel is about 0.5 to 0.7 kW, while the Tesla requires significantly more power when driving — on average around 15–20 kW in everyday use, and up to 370 kW under full acceleration.
I am firmly commited to invent the first horse-elctric drive. Has lots of upsides. You can do plug in vehicles, can charge by sun or grass. Have horse swappings stations along the way to increase range.

So more like 21 Horses.
Because of the detour to generate electricity first. Just let the treadmill directly turn the wheels.
Have you checked whether the 21 horses powered car would conquer the market though? Maybe we’re on to something.

Would be awesome, if the whole Roman wayside inn/horse changing system to deliver fast messages across the continent would make a comeback 😅.
