I'm sorry, I thought the alternative was plainly obvious. Instead of setting probable cause for arrest at an arbitrary number, simply let police use their discretion to arrest who they deem to be impaired drivers.

The problem with that is that accusations will be raised (sometimes true, sometimes not) that officers were arresting people for DWB.

That being said, I think the solution is for police cars to be equipped with video cameras. If there is probable cause for pulling someone over, jurors would be able to see that. And if there isn't, jurors would be able to see that.

I think video cameras in police cars is a good idea for a lot of reasons.
