^^^^minus the ?, the groove is the bailey channel

Yup... more so when you are driving and the air moves the glass into the wrong spot to close properly.

I asked the project manager for the discovery at LR about this many years ago. He told me it was related to turbulence control.

I have seen cars which almost trap some water on the side windows at speed in the rain. Perhaps it is to stop that spot of dead air and keep the window clear?

It stops the glass from popping out when window is opened at speed. The initial opening induces vacuum causing the glass to move outwards away from the bailey channel. As the windows are flat, not curved, the glass is prone to breaking.
Here endeth the lesson

Yep true but all newer stuff now has them as a guide to hold the glass for that first few mm so it dosent get sucked out maby we need it myth busted

Hmm, I thought it was to stream all the water out and away from the window so none of it got into the Defender when it rains.
