Here are few what I feel-
1> ISOFIX child Points- Hardly ever seen proper child seat in use. Kids are often jumping around in their moms laps
2> Child Door Locks
3> Airbag OFF switch- No one Bothers
4> Seatbelts! For the Ignorant Fools.
5> Low beams- Most idiots are driving in HIGH beams only.
6> Cruise control- Due to messy Indian traffic & Lack of long straights
7> Puncture Repair Kit.
8> Max geared speed of the car! I don't think you can maxx out a car in Indian conditions (Or perhaps you have a very crappy car)
