Does the position of a car driver' s seat have a significant impact on driving safety  It probably does  Driving position affects both comfort and the ability to see the road clearly  A driver who is uncomfortable eventually becomes fatigued, which makes it difficult to concentrate on the road
Likewise, the better the visibility from the driver' s seat, the more aware the driver can be of road conditions and other vehicles
It is a premise offered in support of the conclusion drawn in the argument.
