I was driving by the Volkswagen dealership the other day, when I saw that they had placed the letters backwards, spelling ELAS instead of SALE.
Now some people would argue that this was done intentionally, because of the way traffic is coming. If it was meant to be read from people coming from the other direction, it is still a fail. First, because half of the traffic isn't coming from that direction. Second, because even people coming from that direction are reading the last letter first, which goes against the western style of reading from left to right. This isn't written in Arabic.
The word sale would still be best displayed in the correct left to right format, as people coming from both directions would be able to easily identify it.
So if they did this on accident, it is a FAIL. If they did it on purpose, it is still a fail, because it just doesn't make sense, or work from all directions.
