If this pool was a pool of rainwater in the middle of Clayton Road and there was double-decker hurtling its way to Newcastle then it most definitely wouldn't be a myth would it?
Not dangerous, however, if you're planning on pool sex you should also keep in mind (1) will you still be a hunk of burnin' love when your fingers and toes are all wrinkled, and (2) how many kids peed in the pool that afternoon?
