walk-up

Imagine a Kinect sensor on the outside of a vehicle that can: Detect which driver is walking up and adjust the seats and settings accordingly; and then coordinate with their mobile device to scan the calendar for the best route, sync with the ECU for gas stops on the way to work; or recommend you “wait out the traffic” by running errands.This isn’t science-fiction. It’s happening now. We helped one of the world’s largest automakers prototype a similar walk-up experience to push things in the right direction. In Europe, BMW has an app for its new i3, synced with the car, that provides you with alternate walking or public transportation routes if the road is clogged, and will lead you to the nearest electric charging station.


I look up the online dictionary that says that walk-up refers to a building with no elevator. In this case, how to understand the true meaning of "walk-up experience" here? Thanks.

The key to understanding this odd use of 'walk-up experience' is found in this earlier sentence: Imagine a Kinect sensor on the outside of a vehicle that can: and adjust the seats and settings accordingly; and then coordinate with their mobile device to scan the calendar ...

So "walk-up experiences" in this text are situations in which a driver walks up to a car that has an external sensor that automatically adjusts parameters in the car when it detects who is driving.

Please remember to include some reference to the source in the text of your question. Bare links are not enough: Forbes: The Last Thing Cars Need: More Apps, Joann Muller.

I found it confusing, too! I had to figure out that it probably means walking toward the door next to the driver's seat. (And it still doesn't make a lot of sense to me, since the person could walk in that direction and then turn slightly and get into the rear left passenger seat.)

Thanks for your help. It helps me a lot.
