The more eagle-eyed among you may have noticed that there are three motor shows this week, separated by a matter of hours and some global time differences.

If I've got my timings right (and, sorry to disappoint you, but the Autocar office doesn't have three clocks on the wall, all set to different time regions, as appears to be the case for every mega-branded news organisation in Hollywood blockbusters) then the Tokyo motor show will kick-off proceedings, just as the pre-show LA unveilings begin. As Tokyo hits a crescendo the LA motor show will open its doors. And then the Guangzhou motor show will come on stream.

This is, of course, total madness, as the shows and their exhibitors will be falling over each other trying to publicise their wares.

The situation has arisen because of a bout of stubborness, I'm told. The LA motor show date is set in stone because of American national holidays, and organisers stuck to its schedule because they felt launches of the calibre of the new Mini, the F-type coupé and the Porsche Macan gave it a prominence that meant it could take centre stage.

However, they reckoned without the Tokyo motor show organisers. There is an elaborate system in the car world of 'A' spec motor shows and ''B' spec motor shows. Tokyo has long considered itself to sit alongside Detroit, Geneva, Frankfurt and Paris in the former category, but its status has waned in recent years, as manufacturers have preferred to concentrate on the more glitzy and less home-market dominated LA show.
