No visibility issues at all. You will be fine. It essentially adds 2 microns on top of the clear. So anything that has OC on it will be more durable and easier to clean. brake dust will sit on this hardened layer and will only require car wash soap and mitt to remove. You will not need wheel cleaner to clean the wheels.
Polishing OC away is pointless if the paint has been fully prepped and polished before application.
