AR goggles have a relatively narrow field of vision making it less likely to notice peripheral movement, such is critical for driving. They have quite short battery life – just a couple of hours. When they fail, you are effectively blind until you remove them. They can also fail due to a software glitch or crash. Removing the goggles can be disorienting and fiddly. They can be set so that there is little or no passthrough of external video – which would be highly hazardous, even if done accidentally. It's not really possible to establish eye contact with someone wearing AR goggles, which can be important when interacting with a driver. They're also not legal eyewear for driving.
