I have a bit of experience with hovercraft. The only place they can be safely used is over open water or reasonably flat open ground. They simply don't have the directional stability for anything like keeping to a lane or dealing with traffic.
Hills are a nightmare. Going up is limited and requires immense power. Going down requires similar power, but as reverse thrust (or going down backwards). I don't see any horizontal fans in their cartoon, so hills will be that much more challenging. Over ground, the debris kicked up is like what you would get from a helicopter if only you could get those blades even closer to the ground. I suppose over paved surfaces, enough if them would eventually clear all the debris :) The energy required to do direct battle with gravity means that they will never have the range they could have if they just used wheels instead of lift fans. Their cartoon shows it running without a skirt to contain the lift air. I don't even want to think about the power requirements for that. I suspect "hovercar" is a marketing term with as much relationship to actual hovering as the Segway-without-handlebars being sold as hoverboards have with the contraption used by Marty McFly in "Back to the Future." Or worse, it's just another way to separate the ignorant from their money.
