Connected, if I may take a stab at it...
Take two points. Your brain cell. The car.
Connected means minimum delay and intervention between the two.
In e30, brain cell says go, e30 goes. Brain cell says turn, e30 turns, and your butt confirms.
In more modern car, brain cell says go, electronic throttle measures your foot pressure, sends reading to ECU, ECU checks w various assortments sensors and systems (ABS, DSC, ASC, XYZ) to make sure you are not about to exceed the car's limit and kill yourself (because killing customers is bad for business), sends a fax to Germany to confirm, wait for Germany to reply ok,
sends message to EMS to open up throttle, EMS checks and decides whether to engage VANOS or not... and after about 2 weeks, your car responds...
