[802.3_ISAAC] Real live example of why latency maters

[Ragnar Jonsson <rjonsson@xxxxxxxxxxx>]

All,

We have been having considerable discussion about latency, and how important it is. In case anyone was only thinking of this as an academic problem, I urge you to read about the recall of 27,000 Cybertruks because of latency issue with the rearview camera. According to  https://www.cnn.com/2024/10/03/business/tesla-cybertruck-recall-october-2024/index.html:

 

“The rearview display might appear blank for up to 8 seconds when the Cybertruck is put in reverse, according to a filing from the National Highway Traffic Safety Administration (NHTSA). That’s well beyond the 2 seconds required by US federal safety rules.”

 

I think that this is a very strong argument in favor of what TJ has been preaching on latency. This relates directly to slide 8 of TJ’s presentation in Hamburg: https://www.ieee802.org/3/dm/public/0924/Houck_Fuller_3dm_03_0917.pdf

 

I also like to remind everyone of Ariel’s comment in Hamburg, where he pointed out that the 2 seconds are for the whole system, so the camera needs to be up and running in much shorter time.

 

The bottom line is this: Latency matters.

 

Ragnar
