Default Re: Small yet important features missing in Indian cars

Even some top-end models don't have auto-lock, like Jazz VX. Thats very irritating.

Another pet peeve is, why don't they have one touch central locking/unlock switch? In Jazz VX, locking driver side door will lock all doors, but opening driver's door won't unlock all doors. If you have power door locks, adding a central lock switch is such a small thing.

And many cars don't have a dead-pedal. One more small but useful thing

As you rightly said one touch down is easy to implement, but not the case of one touch up.

There should have an extra module called "Anti pinch module" - an intelligent electronics unit, which prevents accidental pinching or hurting while power window is in upward operation. The module is linked to the power window motor and senses motor current. If an obstruction happens to the power window, the motor current gets increased, which will be detected by the anti-pinch module. Based on some algorithms, the motor will be stopped and rotated reversely to bring down the power window. This is a must to have safety critical item - especially with children, so that if their head got jammed, it will result in immediate death.

Would probably require just 2 lines of software code.
I beg to differ with this point. Since most of the automotive firmware have to be complied with Automotive Safety Integrity Level (ASIL), even adding one line of code need fairly a large amount of product simulation and testing, which is a real cost to the company. In automotive product engineering, its not the design or coding contributes the major chuck of cost, but the testing.
