So, we have one of two scenarios: 1. there are a lot of stupid drivers around, who all happen to drive toyota priarses.

Heaven help us if they are brake-by-wire also. -- What is the difference between a duck?

If you want fuel economy, don't pick a Priarse, there are several alternatives that outright use less fuel that it does. If you want to save the earth, consider the significant resources required to mine the materials, then process them, all requiring significant amounts of energy, to create a rather large battery set - even if you never have to replace them. If you want to be revered and cheered as you drive by, well, let's just say the Priarse would NOT be your first choice. > 2. quite likely that there is a fault in the computer control of the > throttle-by-wire, where it seems the computer "locks-up" and no longer > responds to input from the driver.

I'm not quite sure, that's *exactly* what's happening, I've mentioned in another thread how a cellphone had caused a ford (which uses the same steering system as the later Priarses) caused the steering to shudder whenever the phone transmitted. I had an elaborate opinion on the designers in this regard, so I won't repeat it again. Either way, my point was if they're that sloppy, they're going to be sloppy in other areas too. > I hope to hell the brakes in these things are traditional hydraulic > systems directly coupled to the brake pedal. Heaven help us if they are > brake-by-wire also. I've read up on the drive-by-wire steering, and verified there *is* some redundancy in the system. That is, if you lose engine AND power, you will still have steering. I imagine that brakes would be the same. If you press them hard enough, you won't have power assistance, but they WILL work. I also mentioned the likelyhood of idiots incorporated who panic during catastrophic failures, and cause significant carnage, where, the more logical drivers would realise it's hit the fan and actually PRESS their brakes hard instead of get onto the phone whining how hopeless their Priarse is. Moments before they start driving into things.

They show people who can easily help themselves but don't, and then at the end talk about winning a personal trainer, a dietician, and a 'life coach' (and more!) :/
