Doesn't look to shabby. If they have to have something then this looks the best option so far. Might be some weird vortices in the cockpit though. Considering how little of the driver you can see in todays cars anyway, I don't have a problem with losing sight of the driver due to a canopy / cover. As long as the cars are damn fast. But, the on-board shot showing the driver's hands and display, whilst also showing the road ahead, might be compromised. That would be a shame.
