Why no NHTSA front or side crash testing rating?

    Well, they were OEM, but for the RX, not the ES, and really, it didn't matter whether or not they were OEM.

    It happens in more than just Toyotas, too. The interaction of parts in a design isn't always well understood. I had something similar happen in an old Plymouth. The gas pedal was attached to the floor and when I pressed it down it got stuck on the firewall. Fortunately I just stomped it once and it came loose.

    I had an actual case of unintended acceleration happen to me in my 1996 Ford Thunderbird. Car hit a bump on the highway and went nuts accelerating. I was pretty much standing on the brake pedal to prevent ramming the car in front. The brakes were smoking the car was still going at full throttle. I eventually managed to put the car into N and was able to coast it off the road safely but it was a crazy incident. Turned out that a tiny spring in the throttle body body broke and got the throttle stuck in full open position, so it was as if I had the accelerator floored.
    I am sure most of the unintended acceleration cases were indeed user error but I suppose it could still happen once in a while. I had a blown transmission of the incident but luckily no one got hurt.

    There used to be a Chevy car that if the engine mount got loose, the engine could rise up when you accelerated and that it would eventually hit the throttle arm and give it more gas, causing the engine to rise higher and eventually go to full throttle. There were a few accidents before Chevy eventually figured it out and put a little clip on the throttle arm so that if the arm "bent" upward, the clip would pop off, disconnecting the throttle arm from the carb.

    The clip popped off on me once. Luckily I was on a side road when I lost all ability to give the car any gas. I looked at it like it was an indicator that it was time to install new motor mounts. :)

    Ah, what are the two tire types, and which drives better?

    So on my car the 2020 there’s Bridgestone ecopias and they seem to drift different directions white on highway speeds and sometimes even on the streets, my wife’s 2019 is equipped with Toyos and her car is straight as an arrow and has a substantially more comfortable and seemingly sturdier ride

    But I still drive my car for the Apple CarPlay! Call of Duty sounds amazing and the surround sound helps me seek out enemies easier!

    Good thoughts regarding tire types.

    FWIW, I can’t immediately recall any tendency to drift to either side with the Ecopias on neither our 2009 nor nor our Prime. That is, assuming they are inflated evenly. I have noticed a tendency to drift to the right with the Michelin tires we had previously on our 2009.

    We don't know why he didn't do this (or tried but didn't succeed), but the zig-zags and gating that some car makers put on their automatic transmissions may have interfered, especially on an unfamiliar loaner car.

    We DO know, from a passenger 911 call, that he tried unsuccessfully to shut down the ignition. But being unfamiliar with the car, he didn't use Toyota's specified method, which is to hold the power button down for 3 seconds. That is an eternity in this sort of emergency situation, many panicked respondents would abandon that path before the required 3 seconds and move on to try something else.

    Toyota has since programmed newer cars to recognize his repeat-button-stabbing pattern has a valid shutdown command.
    Your memory has forgotten a whole lot more unfavorable results found by others. Do read Trollbait's response.

    NHTSA's passenger car brake performance regulations allow greatly increased braking distances when the vacuum booster supply is depleted, or the brake assist system suffers other failures. But unfortunately, the regulations (at least at that time) covered only the case where the engine went to idle, not to wide open throttle as this Lexus did.

    The models tested, or not, are at NHTSA's choice and discretion, not the car makers' choice. But NHTSA simply doesn't have the budget to test them all.
    In my local area, it seems that something of this sort happens nearly every other week or so. But most of the drivers here fess up to driver error, such as pedal misapplication.

    There are some patterns: (*) driver ages are skewed towards seniors; (*) there are no apparent favorite car makes or models, incidents seem to be well randomized across the entire available market; (*) manual transmissions are very seriously underrepresented, even after accounting for their low market share.

    Of course that is the tact taken by Boeing in the Max 8 so maybe not the same.
