There is nowhere in the world with no waiting time in A&E. It's just not possible. You would need dozens of doctors and nurses hanging around, doing nothing most of the time, so that - if an unexpected surge hits - they are free to deal with it.
The problem is actually completely the opposite of what you are suggesting. There is too much focus on A&E waits, and this skews spending decisions, so that not enough money is invested in services that can keep people out of A&E (social care/primary care/public health) or in services that free up ward beds, so that patients can be moved through A&E quickly, freeing up space (social care/care homes/community hospitals).
If you really want to save lives and reduce A&E waits, you need to invest in hospital wards, social care, care homes, primary care and public health, not in A&E itself. And I say that as an A&E doctor.
