If sales day -- the day carmakers reveal their monthly U.S. auto volume -- coincides with Election Day, should reporting wait another 24 hours? Automakers are splitting their ballot.
That creates the first two-day sales day since an identical coincidence in 2004.
At last report, a dozen brands including Hyundai, Subaru and Volkswagen are planning to stick to Tuesday, the same day American voters will determine which political party will control the U.S. House and Senate and 37 state governorships.
But the Detroit 3, Toyota, Honda and several others switched to Wednesday to avoid any potential conflict with the election, which is unusually contentious and partisan this year.
Whenever October sales are reported, most analysts expect them to be stronger than September's seasonally adjusted sales pace, and perhaps the best annualized rate since the cash-for-clunkers spike in August 2009.
But most consumers seem unlikely to notice. Automakers' sales-reporting decision may simply be picking when to be ignored -- in the coverage blitz of election day itself -- or of election results on Wednesday.
