I forgot to mention something that helps support my case: you can't put the car in reverse without putting your foot on the brake. So, it goes to reason that you can't mix up the pedals when you have your foot already on the brake.

I'm afraid your wrong. I guarantee you this is not a case of driver error, because I've seen the evidence, and I know someone this affected. My dad (who taught auto mechanics for 30 years) has had this happen to him twice now with his new '09 Toyota Tacoma. Both times he was backing out of the garage, and the truck suddenly lunged backwards, tires spinning away. Thankfully he was calm and collected enough to hit the brake and shift the car into neutral while the engine decided to its thing. If this just happened once, I might be inclined to think that it was driver error, but having the exact same thing happen twice pretty much rules that out in my head. On another note, my mom, who's never been the cause of an accident, recently ran into the side of a building with her '06 Toyota Avalon when it suddenly lunged forward while she was parking. Now, my mom's incident I'm not so sure if it was driver error or not, but it's suspicious all the same. In any case, there's nobody I'd rather have drive a vehicle I'm in than my dad, and I can assure you that this is much more than people being 'ignorant drivers'.

It really isn't that far fetched to think that there could be a bug in the software that drives the throttle. It could be something as simple as a division by zero. Obviously, something in the code is getting the wrong data that the coders didn't take into consideration.

Two Points:

1. How the heck would you enforce this? If there's an open relay in Sri Lanka, how could the US possibly "tax" it?
2. There's another system in place that has this "tax" you speak of, and it's called the USPS. I don't know about you, but I sure do get a lot of snail mail spam.

In the end, taxing e-mail is nearly impossible because the internet is a GLOBAL system.
