This is perhaps too familiar a situation for some of us:
I didn’t realize I’d got the car in low gear (I can’t always feel that and I didn’t look) but when I tried to accelerate to 65 it complained badly and the tachometer spiked up and I momentarily panicked — was my car going bad? Was I going to be stranded in the heat? Luckily the road was largely empty so I hit the brakes and was able to upshift quickly and then things were OK but yeah.
Automatics are unforgiving at times, but so are manuals. About 1984 I was darting down I-40 west of downtown in a borrowed Saab. Now about the only thing I knew about Saabs was that the ignition switch is between the seats. Obviously I passed that test, but gawd, was that engine loud for a modest 55 mph.
Wrong-O, Buffalo Bob. I’d confused the tach and the speedo, and I was darting at 5500 rpm, somewhere on the wrong side of 80 mph. I got myself straightened out about a mile and a quarter from the nearest radar.
