I don't own a car so can't stick my head under the driver's seat to verify, but it seemed like many recent cars has:
- Reporting features for brake, gas, steering inputs, a la SNMP
- Computer assisted brake, with a backup linkage
- Fully electronic gas pedal, with a speed sensing cruise control
- Electric/electronic power steering, using a torque/relative deflection sensor
These features are case-by-case:
- Command based "write" access for brake/gas/steering
- Absolute steering position sensor
So a lot of older cars require special spliced cables to fake analog readouts or nonstandard digital links to retrofit a self drive, and newer cars still needs to be purchased with those input features enabled as well.
