Implement user-configurable delay (in increments of 0.1 sec) for voice alerts
Some vehicle Bluetooth implementations have lengthy handshaking which prevents the first second or two of Waze voice alerts from actually being heard. My car has a feature that ramps up the volume of a Bluetooth phone incrementally on first connection. However, the impact is that in most driving situations, the first two seconds are simply too quiet to be heard!
For example, instead of "In 500 metres, turn right onto Main Street.", all you hear is ".. to Main Street". Obviously, this information is unclear and confusing, forcing the driver to glance at the map on the phone to verify what exactly is being directed - not only annoying, but it unnecessarily compromises safety!
My suggestion is to implement a feature where the user can configure a number of tenths of seconds delay for voice alerts, during which Waze would actually transmit silence - the default delay of course would be zero. This would satisfy any in-vehicle delay of the sound due to handshaking latency or any reason, while having no negative impact on any user who doesn't suffer this problem.

Fully agree, this is a problem on both of our vehicles (which are old enough not to have CarPlay).
