The dog's response then becomes probable cause to search the car.

If the "suspect" insists on it, wouldn't they still be required by law to get a warrant?

I don’t believe a warrant is required if the car is not opened. I could certainly be wrong on this, but I believe a dog alerting on the closed car is considered probable cause for a physical search, just as it is at a border crossing.
