Lock him up. At 148mph you travel the length of a football field in about a second and a half. A farmer in his truck gets on a rural two-lane road that from his vantage point is clear and death could easily ensue. Hopefully only the life of the nutcase driver, not the farmer or an oncoming vehicle.
Had a similar non-fatal like that. I was a passenger, driver started nodding off. I woke him up, he slammed into the truck. Luckily the steel rod in the sunvisor glanced back off my chest sideways only leaving a deep scratch, but the driver cut his forehead open on the windshield through the steering wheel.
