Now NASA is involve! ************** - Seems like Obama has cut their space budget. Maybe this is a way to "create jobs" at NASA.

Maybe this is a way to "create > jobs" at NASA.- Hide quoted text - > > - Show quoted text - The problem with the cosmic rays theory is that it would effect electronics devices everywhere so you would not just have runaway Priuses but other electronic devices going nuts too. From what I've seen so far the Prius electronics seem to be shielded and protected as well as any other car. The funny thing is that the 2005-2008 Prius (2nd Gen) is designed and built more like a conventional car than the 2010 Prius (3rd Gen). which has no reported brake/acceleration problems (other than some speed freaks still think it accelerates too slowly) It's time like these that I wish we had a clone of Dr. Feyman - so we could ask him - "Hey, Mr. Wizard can you explain all of this?" |
