A C Hack

In a futuristic city you don't hail a taxi
Simply dial for an autonomous car
Still identified with yellow chassis
Now manufactured by Jaguar

Self driving auto prowls the street like a cat
Looking to snatch a passenger
You use an app to pay for that
Just beware there's no driver

Once it arrives vocalize your destination
You'll be whisked away timeously
When you arrive pay more than attention
Doors won't open unless you tip generously
