A few weeks ago. my wife ignored a Waze suggestion to avoid a particular interstate, resulting in a tire ruined due to a pot hole. Perhaps the state of California would prefer to be held liable for all the car damage incurred due to their interference with free commerce.
One thing that Waze does, which I do not like, is select a circuitous route that seems to it to be 30 seconds faster but is more stressful and often slower. For example on my way to New Jersy from Long Island its sent me into mid-town Manhattan at 4:30 in the afternoon on a Thursday to have me cross busiest traffic area to get to a tunnel because it saw a 10 or 15 minute backup on the Belt Parkway in Long Island. I would have gladly sat in traffic for 15 or even 20 minutes to not have gone through that. Another time it sent me through the ghettos of East New York and Brownsville to shave five minutes off my ride, which basically didn't even work because of traffic lights. But it did shave 5 years off my life, so there's that. Basically when making that commute now I just ignore Waze and take my preferred route and use Waze for alerts only.
