Welcome to Car Seat Data.

This site contains information on vehicle ergonomics. Some car designs are a compromise which may be responsible for producing pain and difficulty for the driver. This site contains papers which discuss the problem, and data on vehicle layout which may help drivers select a suitable model.

Comments and Suggestions

Please send me mail telling me what you think about this page and how I might improve it. Please note that I cannot answer questions such as “What is the best car”. The information on these pages is designed to help you make that choice, but you still have to find the car that suits you. People come in all shapes and sizes, and what suits one will not suit another, so there is no such thing as the “best car”. However, there are some "lemons" to avoid!
