I can remember passing a old farm truck on a moonless night on a two lane Farm to Market Road. I could see oncoming headlights, but they appeared to be far enough away to insure my safe pass.
I accelerated but stayed in 5th gear. Just as I drew abreast of the pickup, I realized that the oncoming vehicle was much closer... I grabbed 4th and pegged the throttle...
The oncoming vehicle was a Jeep CJ-5, with headlights mounted closely together, just outside of the grill. The narrow headlights made the vehicle appear to be much farther away.
It was a hellova wake-up...
