The EV race is about to get a brand new, low-cost entrant backed by Billionaire Jeff Bezos. It's called Slate and it offers a bespoke style of electric vehicle that starts as a blank-slate, two-seat pickup truck for about $25,000 before incentives. Each buyer can then add accessories, like side-stripes, stronger bumpers or infotainment screens, and you can even change that little truck into a five-seat SUV. Chris Barman, the CEO of Slate Auto, joined Bloomberg Open Interest to talk about its business model and how it hopes to take on EV giants like Tesla.
