Chinese "Future Mobility Corp" is still a wild shot in the air
Not really, Tencent is extremely famous, it's like Google here. You may not be aware that literally most vehicles on the road here in China are electric already (though most are bikes, there are also buses, taxis and tractors).
Maybe they have and I'm sure there are some very attractive offers on the table there.. But I don't think that BMW treats its engineers badly either.
For a german (bavarian) engineer, working at BMW is a badge of honor, while the Chinese "Future Mobility Corp" is still a wild shot in the air.
So while some will try the greener pastures at the new startup, most will probably not be swayed.
Again, wild speculation from a non-german non-engineer, please correct me if I got it wrong.
