do you really want to debate regenerative braking systems? Price out your prius brake components and lets compare.
I wouldn't brag to much about brakes on a prius. There have been so many complaints that the Japanese government ordered Toyota to start an investigation into the problem.
Ever do a brake service? If you don't perform one every year on disc brakes systems you will continue to have the same problems. From what I see, it's usually not the car's fault but rather lack of maintenance. Owners don't think its needed because its not listed in the maintenance schedule.

Battery Dead Over Night
The bulk of the vehicle electronics get the battery voltage always. They are supposed to go to a low power mode or sleep with key off, RAP off. Maybe something is refusing to shut itself down. A problem like that is hard to diagnose since the act of pulling a fuse may reset whatever was drawing the current. Ask them to try disconnecting power to the OnStar VCIM (not something indispensable)?

I have a 2010 Traverse in Sept 0f 2010 car would not start called road side assistance to get a jump took to dealer and said could not find problem but neede to keep car locked when not in use to keep it from happening again. Last week in Feb 2011 same thing happened again took to dealer, one week later happened again. They gave me a loaner over the weekend and they still can not find the problem. I have the LS version with no nav or other accessories to drain battery. I was also asked if I had the Blackberry feature and I do not. I don't leave keys in ignition, I very seldom charge phone in the car and when I do I unplug the charger. I know the charger stays on with the key out so I unplug the charger. Does anyone have any ideas or is there a fix. I am going on a week long trip and the car will be parked for one week hope is starts when I ge back!!

do you have any aftermarket devices ie remote starter, chargers etc. if yes, fully charge the battery and unplug them and see if the problem continues. aftermarket modules add 15mamp draw and if wired in wrong the modules don't go to sleep.
What draw measurement did they have?
