You won't get stopped, never mind cautioned for making use of the available road for vision and vehicle stability. Go and undertake a couple of day's instruction from a Class 1 Police Driving Instructor. (

Traffic police are generally very measured and sensible when it comes to such issues. OK, if you're doing 105 in a 60 limit they'd almost have to query it and report you if there's enough evidence to do so.
The police driving the smaller cars can be a bit silly at times. But they have minimal knowledge of traffic law so you're unlikely to incur much more than a bollocking.
