Earlier quoted context omitted.
My trick with their system is to just look at every car, click through to the final receipt screen and then go back to find the cheapest one. It's a bit tedious and deceptive to the customer to present variable fee at the last part of the checkout process. Probably the worst modern "dark pattern" that I hope regulators take a look at.
I share your sentiment, but I'm not sure there are any legislators I trust to understand or regulate dark patterns effectively.
It doesn't take a world-leading regulator to say "it is an unfair and deceptive business practice not to list the total price in a search result."
I think a regulator may be able to handle this one.
