Hello George, yes, it would be very interesting to have data about distribution of links and lengths in cars. I have not seen such data for the industry overall. In our case, we would need it specifically
for sensor links. If any cable/harness manufacturer has respective data they could share, that would be very interesting. One thing I would like to point out though: Sensors (including cameras, and displays for that matter), have very limited variability in respect to their placement inside the car. Also
large processing ECUs have limited options on where they can be. The dimensions of the car are typically not influenceable by the engineers concerned with electronics. This means that we have very little to no influence on the link length we need to support.
Kind regards,

Yes, no tearing of your head, just a big thank you for sharing this. I was searching for the relevant presentations. These appear to quote far more than 15m as the need, but highlight that we may very well need to
choose what types of vehicles we are targeting. I was hoping that given that we’ve had some deployment experience and some changes in architecture moving towards zonal cars, we might have some better defined data with a distribution of links & lengths. There are many
examples in LAN cabling – see, for example, slide 19 of
