Wow! CeBit exhibition was down almost 30% from last year and nearly 50% from its peak. And, though I heard official numbers put attendance down only 20% from last year, it seemed to me more like 50%. With the number of backpacks that seemed to emerge on Thursday and Friday, I wonder if attendance was inflated with students.
All of that being said, automotive was well represented with booths and / or attendance by GM, Audi, VW, BMW, PSA and others. Tier 1s, Continental and Harman Becker, each had demonstration systems . . . with the HBAS system far more responsive and impressive (see video comparison)
I would have compared the GenIVI Linux based solution, but as you can see from the HBAS video, Intel is still pushing the QNX based demonstrations as the Linux system doesn't yet exist. ;)
