Thanks, Malcolm, for the interesting historical perspective. All these real land speed records are worthy of celebration.
By the way, the standing start kilometer record (non-wheel-driven) was set by the late, but still great, Dave Anderson in the Pollution Packer rocket dragster.
Set on September 30, 1972, this long-held FIA record is 234.775 miles per hour, or more correctly since it was the kilometer, 377.834 kilometers per hour.
Absolutely correct that Americans don't know what the kilometer is.
But that was quite an achievement accomplished, per the rules running in opposite directions (Bonnevile Salt Flats), and completing the record runs within one hour.
While the SCTA and USFRA records are quite another type of record, they are also independently timed and run under a very clear set of rules.
These also are legitimately celebrated along with their creative cars (and bikes), competent crews and brave drivers.
