Increasing complexity is not what's concerning here. Being able to adjust the ride height of your car (air suspension) is not that uncommon. My current vehicle has adjustable air ride suspension for city/highway. It automatically drops an entire inch at speeds over 60mph to reduce drag and allow for a lower center of gravity. It's great. The concerning issue here is someone hacking this vehicle's OTA software update and causing accidents. Or even tapping into the vehicle control system(s) and causing havoc. Unlikely, but possible vs. current vehicle technology requiring a trip to a dealer by an authorized and authenticated trained tech to make these changes. I imagine every critical system on the Model S is accessible wirelessly. This actually bring me back to Michael Hastings accident where theories are floating around that steering, breaking and acceleration systems might have been compromised wirelessly causing the accident. The bottom line is that there's simply way too much convenience technology in cars today and that might not be such great thing. It's a tough call as safety technology is important and the more the better. However, certain things such as OTA suspension and other critical system updates need to pushed and completed intelligently. I want to assume that any updates to these vehicles are done when they are off (overnight) and redundantly checked for integrity to ensure the update was successful.
