HMI is an interesting field (Human Machine Interface which was MMI back in the chauvinistic dark ages), the way we interact with machines. Ever notice how some software just seems to be easy to run/navigate even though it has lots of features and can do lots of stuff? That is usually no accident but a result of careful design, often evolved over time with input from users/testers. Same story with lots of machines and such. Some are easy to master and some may make the designer happy but no one else.

Luckily in the automotive world the brake, clutch, and throttle are in the same order from vehicle to vehicle and clockwise rotation of the steering wheel turns the vehicle to the right.

Web design can be an interesting task. Good luck to you with your site.
