I was watching a Cash Cab rerun on GSN and in the rerun I noticed that Cash Cab did a Double Ride and I had never noticed these before. Is Double Rides something Cash Cab did occasionally when they had twin contestants playing and if twin contestants participated in a Cash Cab Double Ride Ben Bailey mentions that the money the contestants win is doubled for them
How did Cash Cab Double Rides actually work?

Hi, Bestie! I don't know. I never saw a double ride. I will keep my eye out for one and report back to you.

The double rides are randomly selected episodes, and not necessarily twin contestants.
