Hi Muhammad Azhar Hussain,

You have NOT mentioned what kind of car.

Is it a vehicle or a toy car ? Is it a 2 wheeler, 3 wheeler, 4 wheeler, 6 wheeler, etc. ?

Is it a vehicle that runs on the road carrying people ? How many people: 1,2, 6, 10, 20...?

What kind of engine does it have ? Electric/Petrol/Diesel..?

What is the Electronics already built into the car ? OR is it that a car manufacturing company has approached you to develop all the electronics inside the hood ? How familiar are you with the Electronics and Mechanical components inside the car ?

P.N.: OP has NOT posted NOR replied after the first post since last 15 days....and members are giving their opinoins..and disussing, and discussing, and discussing....Where is the OP ?

Edit:
To the Moderator: In this kind of situation I would definitely like to have a grading system which will atleast give me past information about the OP when a new idea pops up into his head to waste our valuable time.
We will know "how seriously" to take his new post. The Karma system, NOT for the good replies, but definitely for posters who LIGHT up the FIRE and dissapear from the face of the earth.
