$200 happens to be the difference between level "2" and level "B". Level b does not come with BSM sensors.
Which of course as we all know, when this all blows over and things go back to normal, I'm sure FCA stellantis will be happy to take $200 from you to install what you missed out on due to the shortage. Surely, that's all it would cost to add that back in at the dealership.
