Hybrid cars

Be careful of those figures. You can do some simple sums. You need about 12kW to run a medium sized, medium streamlined motorbike at 70 mph, so a 20kWh battery will last for about 90 minutes, so around 110 miles as long as you don't have the wind against you.

Bet one thing won't change though. Bikers will still be at a greater risk than car drivers. Will we even hear them coming!

You are absolutely right.
The combination of older ebike riders who generally have less than perfect hearing and near silent electric cars makes a potentially lethal mix.
Instead of the car driver saying, "Sorry mate, I didn't see you", it will be the bike rider (assuming he/she survived) saying, "Sorry mate, I didn't hear you".
