>But why would you have to buy a 4G router just so that your car can download an update? Sounds needlessly complicated to me. I perfectly agree with you on the fact that it represents an example of poor (actually extremely poor) management of the customer assistance and that Tesla should have provided quickly (and hopefully politely, avoiding the small economics lesson that sounded - at least to me - a little bit patronizing) a solution to the issue. But I was approaching the issue at a slightly different angle, the OP on the forum has two cars, of a value of nearly or around 200,000 US$. Their income must be proportional to that, the 3G/4G router, might be worth 60-70 US$ if DIY, and possibly 100-150 US$ if having someone configuring it, i.e. a minimal fraction of their income, if I had those two cars and felt the need to have the road maps updated in a timely fashion, I would have first solved the issue. The fact that for a tag price of 80,000-100,000 US$ per each car I would expect not one but two (one under the driver and one under the passenger seat, in case the first one doesn't work) such little modems as a complimentary courtesy by Tesla would be secundary to solving the problem at hand and have those maps updated.
