I'm on travel, without much time (read: too lazy) to update.
Enterprise got me into a new car the very next day (as expected,) a new Focus. It was either that or a Camaro. I had a Camaro drop-top 4-5 rentals ago and found visibility to be much worse than even my wife's Civic coupe, so that was out. I didn't find out until we walked out that he also had a Fiat 500, which I had 4 rentals ago and liked a lot (as a rental.)
When I have time I'll respond to specific questions. For now, just a few comments:
After I shut off the engine it was never started again. A good samaritan helped me push it onto the shoulder, and the last I saw of it was the tow-truck guy hooking-'er up as I was driven back to my hotel by the awesome local police officer. As an aside, did you guys know that the back of a cruiser is nothing but hard plastic? Makes sense now, but I had no idea beforehand.
Some of you stated the throttle may have stuck at part throttle, but it felt more aggressive than that. Unfortunately, I shifted to Park and shut'er down as soon as I realized what was happening. Couple that with the "fog of war" and the details (other than what I posted before about the RPM and behavior I noted.)
The Focus, from what I learned in another thread, has a similar dual-clutch AT, but though the one in the Focus feels a lot more refined. It may be the additional mass of the larger Focus, but it feels more like a traditional slush box than what a "manu-matic.' It may need an alignment with 37k miles on it, but I found the Fiesta to handle much better than the Focus. The Focus wanders and tram-lines a bit and even seems a bit louder, even though the tires seem as new as the ones on the Focus (my previous Yaris rental had nearly bald tires and I flew in during one of the last ice storms here in the Midwest. Luckily, I was able to walk to work every day, though that didn't save me from injury - I ate it Home Alone-style while walking to the office one morning!
