Sun Blockers

Please make sun visors that are fully adjustable. I'm referring to when they are blocking the side window, and you can pull them back and they will slide to where you want them to be.
Please also tint the front window above the rear view mirror. morning and afternoon sun can be very dangerous and these features will give drivers the tools that are needed to make sure sun doesn't cause them to get in an accident.
These features should be on every model, and standard.
