Trademarks are about confusing names in a similar product market. Just having a similar-ish sounding name doesn't mean it violates the trademark. Self-driving cars are pretty different market to home security cameras.
You're thinking of Waymo :) Waze is a crowdsourced traffic & maps thing. It's vaguely, if you squint, adjacent. I don't think it would be completely crazy, for example, for Waze to introduce a line of dash cams.
