You're riding in the UK though. In ABROAD, where the FOREIGNS come from, people actually respond to bicycle bells in a consistent and useful manner. You end up ringing them quite a lot if you want to make progress on a fietspad or Radweg.
You're confusing your Foreigns. Here in Amsterdam the purpose of a bell is to go hand in hand with the yell of ****-Wit, or other appropriate profanity at the gormless tourist, or worse, gormless local, who seems to think stopping in the main gateway to the fietspad through the busiest park in Amsterdam at 6pm is a good idea... Or the Tourist who hasn't realised that bikes here do not give way, and just steps out blindly...
Once you leave the big cities tho, everything you say is valid, it's just anywhere with tourists or students you have to augment it with other methods...
Oh and then there's the Brommers.
