Google self-driving cars are better than Californian drivers.They don't accelerate quickly, they don't speed, they leave plenty of space and are very polite to pedestrians.
Difference between driving a car and using Google owned self-driving car is like difference between kings carriage service and owning a horse.
Did you accidentally flip the second part of your analogy? It doesn't really make sense to me as stated..
Indeed, but as I was comparing differences (difference remains the same regardless of the order of the compared), I thought that it actually does not matter and it is understandable from the context.
