Successful enough for me and many other people I know. End to end from my house to grocery store, kids schools, friends houses, etc. Multiple times per day for the past year.
It’s not perfect but I’d consider it a smashing success for something I rely on for safely transporting my family every day.
Define safe? Would be interested to see you provide a benchmark that is reasonable, and lock it in now so we can see if this statement is falsified in the future.
