Why every road in Taipei should have 8 lanes

The 1st lane is used for parked motorcycles and bikes, because often the side-walks just don't offer enough space and people still park there anyhow.
The 2nd lane is for bikes (completely isolated from any other lanes, otherwise motorcycles and car will park and drive on it)
The 3rd lane is for parked cars
The 4th lane is for double parked cars (because this if often more normal than an exception)
The 5th lane is for those litte vans, taxis and buses to pick up people
The 6th lane is for motorcycles, because I really hate them being spread all over all the lanes riding at 60 to 70km/h and drive so very close to my car and damage it
The 7th lane is for cars which go straight
The 8th lane is for cars which need to turn left.

The last reason is that 8 is a lucky number, so it's easy to remember.

We could reduce this to 7 lanes, if car parking is prohibited, however, car drivers ignore this, so still need one lane for parked cars.
