On the road again

Ever since we started playing the ‘Consecutive Number Plate’ game, we’ve noticed a very strange phenomenon. You will go for days and days looking for a particular number, but as soon as you’ve spotted it (hurrah!) you will almost immediately see three more. I first noticed that with the number 3, but it has happened several times since (we decided that as far as we were concerned that ‘02’ and ‘03’ didn’t count as 2 and 3 – they had to be single digits. Whether that’s in the official rules I don’t know). And are there any number 13s anywhere? Between us we’re on the road for about 3 hours a day, in three counties, so we must have a fairly high chance of spotting the darn things!
