Some out there are pursuing non-ToF systems:

Also, your accuracy is very dependent on the baseline of the laser vs. the image sensor and it's very sensitive to proper calibration.
Plus expect some scale changes in the output data when the thing heats up or cools down.
Any laser scanner you'd put on a vehicle is going to be ToF, as far as I know. While this is useful for indoor sensing, you'd completely wash out the laser illumination once you have to compete with sunlight.
This would be better described as a structured light scanner. The principle is more similar to what something like a Kinect uses than a Velodyne/SICK/Hokuyo etc.
