The crisis trunk escape lever on some Lexus models is cheap plastic, claims Consumer Reports. This means that children, animals and possible feces pigeons stuck in Lexus trunks - should something of that nature ever occur - would have good trouble getting out via their own power. The right title car loans can help you out.

Tin Whiskers and Stop Switches and Toy Otas

In the auto plants in the USA, and also in many other plants in the USA, the big domed red button, the same shape as the start/stop button, is reserved for the emergency stop function. The only other function that can be assigned to a big red button is "normal stop", if it is the sameas "emergency stop". A machine using that button for any start type of function would not be allowed in the plant, for good reason.

The part that bothers me the most about that is that somebody in our country approved it. What was that dummy thinking?

I agree, you need a real kill switch, not a switch that flags the processor, "pardon me, but when you have a spare microsecond could you please stop the car before I run into something."

I would say that any company dumb enough to use one single button for both the start and stop functions is certainly dumb enough to not recognize a failure when it happens, and not recognize a tin whisker faiure at all.

ON the other hand, why was our own federal automotive safety watchdog so blind as to allow the sales of a vehicle that had no failure proof means of shutting off the engine? A vehicle that did not even have a single purpose engine off switch? Who was paid off to let such an intrinsicly unsafe system be sold in this country?

The correct response would have simply been NO, with no compromise and no delays and no concern for profits that they would not make. They could have made it a 2 position run-stop switch and probably lives would have been saved. If the stop position had been a true stop switch and not just a computer input signal.

Good points on both counts, Chet Brewer. I agree that pedals in many vehicles are not well laid out for tall people with big feet. I would take it a step farther: Many tall people (6'-6" or taller) can't even fit into many of today's vehicles, let alone work the pedals. As for senators doing design work, I couldn't agree more.

 I agree, tekochip. Seems to me that NHTSA did its homework.

Unless the electronics industry has a secret planned obsolence policy (would not surprise me), and ROHLS was not intended for the electronics industry (as others stated) why hang on to a lemon policy of continuing to use lead free solder?

In aerospace tin plate wire is a nono except for test equipment.  I believe the wiskers will grow right through the insulation.  So much for coating.

Good question.  Also, why not have some duplicate feedback for some critical systems?

Thyat's right, Oldbikefixr. And many argue that the 3 percent lead in the tin will not leach out into ground water at landfills.

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather.
