Basically the software is to update a computer in the car. When you do an update for a PC it can take a long time to download but the installation takes just a couple of minutes.
What I was told this morning is that they had started the update and it would take about 45 minutes and that once it was started they just had to wait for it to finish and sometimes the system would run slowly.
So it looks like they have to make a connection with a server, wait for the download, which might be slow if there is a lot of demand on the server, and then install it.
Not a very sophisticated system for 2025.
