An adjustment, as in straightening a wheel, is not damage. It is an adjustment this has been held on many occasions in relation to criminal damage, however, the principle applies.
Ok, you don't know if there was any damage, fair point, but whether she should have given you her details is for a court to decide in these circumstances. We are getting into the realms of reasonably help belief.
"I honestly believed there was no damage", would a court accept that?
I don't know.
I suspect that the previous case you allude to was significantly more serious as I really cannot see the CPS going ahead in the circumstances you describe.
As for your allegation that the contact was deliberate.
Very difficult to prove, but if it were the case then you are into assault rather than RTC.
