Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Dt: the accelerator and the brake pedals are to close together. The consumer thinks that one should be up higher than the other. When you wear work boots, that is more dangerous. When the consumer hits the brake, if you're not sitting up straight, the consumer's foot is hitting the accelerator also. The consumer is trying to remember to keep his foot far enough over.”
