Well, power needs to be delivered to supercapacitors via metal contacts. You’re going to reach physical limits of voltage (safety, isolation distance) or current (conductor cross-section) that can be reached inside the space of a car way before you reach the 100MW mark. Even the 2.2 MW delivery system is not something to drive over, the connector is probably a set of big metal pads that a spring or screw holds together. And not all supercapacitors can charge in a second, it’s usually a trade-off between power capability and energy density. Think 10 Wh/𝑙, about 40x less than Li-Ion, for charging below 10 seconds.
If you’re considering things this far-fetched, just forgo onboard storage for highway trips and build a trolley system.
Pairs of wires like for trolleybuses are required. Grids are for free roaming in an area, which almost nobody needs, and only work when the traction surface is conductive, at which point best just build metal-on-metal rails.

Well my next idea was going to be a metal grid above the motorway like bumpercars.
