Just to prove I’m not going mad here’s a video.
Sorry about the quality, turn volume up, first shows correctly installed, then incorrectly and how hard it is to get off and how it could easily be mistaken for being locked on.
https://youtu.be/h5JQWO8nv0AThat is a scary video... Very.
This horrid accident clearly asks questions about the steering wheel fastening....
I had a removable wheel on my Lotus. It had a very simple push on to the see/feel that 2 opposite red 'studs' had popped out, indicating the wheel was correctly and securely fastened... but even then, always gave it a big pull and wiggle to check...
I hope MMC quickly get on top of this. I had not realised that a removable wheel was standard/or an option.... Can the car be 'lived in' with a standard fixed wheel?
