5 stars: Great app. Simple and effective. Within 20 secs of driving it engages, silencing any calls and texts. When you stop driving it stops and calls ring as normal. It would be great if there were the facility to easily pause the auto start feature for a given time period for times when you are on public transport or are a passenger - after the pause period the auto start system restarts. That would make a great app even better!
4 stars: So, it's a great app without bloat. It switches on within seconds and off again shortly after getting out the car. You can customise the message and people seem to appreciate knowing why I am but answering the phone. However, it frequently unchecks auto-start and auto reply (which means it then fails to turn on, and then the phone rings!). Sort that out and it will be five stars.
5 stars: Drive Safe is not bloated with features and functions to add unnecessary complexity. With Auto-Start it just detects when I am on the move and stops me taking calls and answering texts. This allows me to drive safely without distractions. Full marks to Andrew Irwin

It does not disengage when you leave the vehicle. You have to manually start and stop it. It responds to every message whether you are in a car our not. I don't have phone calls toggled, but have not received any while this ...
