The homes all appear to have built in the mid-1980s to today, but my guess is that the streets were laid out or planned-out much earlier than that. The 12 Hours of Sebring was a stop on the old FIA World Championship of Makes, as well as that first United States GP in 1959 (although, that was a one-time thing).
Still, seems odd (yes, even to me) that there's a Lexus Street and not a BMW nor Audi Street (which has a much richer international motorsport history) or even a Cunningham Street (winners of the first 12h of Sebring), but my guess is that having a non-thru street was rather confusing, and someone (or a group) re-named it to something that sounds nice.
To see a road named after Osca or Vanwall does make me smile, as they're quite obscure teams from the past.
