Vent are never a problem as long as the proper drainage systems are in place, as well as a mesh. Not the first time a car maker has done this. It`s just about the least of our worries. The upside potential it has with cooling far outweighs any negatives that may come as a result of its construction.I don't think those handles move, just sticks out a bit permanently. Would make sense for them to retract once the car is reversing but that wasn't the case. Then again this is the concept model, but if it's not on a concept I don't think it'll suddenly appear on the production model.
As much as I like the large hood indent, I can just imagine all the snow and debris that's going to collect there.
