Electrifying the road might sound like a dangerous idea, but the tech has been designed with a few measures in place to protect humans and animals that might walk across it. The track at the surface is earthed to prevent shocks, with the conductor itself buried deeper down – and even then only short sections are powered at a time, as vehicles pass over them. To get zapped, you'd need to be on your hands and knees jamming a fork between the rails, in which case the more immediate danger would be the car speeding towards you.
