Jim Cramer was a self-professed skeptic of driverless cars. That opinion changed when he got into the passenger seat of one at Alphabet's headquarters this week.

"I thought they were a pipedream, something that wouldn't be viable until the distant future. Turns out I was wrong, and the future is now," the "Mad Money" host said.

After a short ride in a Waymo with someone chaperoning in the driver seat, Cramer's entire opinion about driverless cars changed. He realized he trusted the technology more than he trusted a driver to not drink, text or fall asleep at the wheel.
