IMO, having an indicator of some sort, in the field of view, that alerts drivers to vehicles occupying their blind spot can do nothing but aide in situational awareness. I do not see that being a bad thing, unless for some reason the system tends to malfunction. For that reason alone, I think Tesla should update the software to be more in line with other auto makers. The last three car's I've had (all of which are significantly cheaper than my MY) all had active systems (visual and audio alerts) and they all helped quite a lot. Honestly, there should be a light located high near the outside rearview mirrors like most cars. Who wants to look at the center console to see if someone is in your blindspot?
