It's possible, but given the cyclist approaches from the right of the screen and cycles straight past PR's car and out the left of the screen, I don't see any reason to believe they are connected. They seem oblivious to each other. Unlike the departing car, of which PR does seem aware, and is possibly avoiding.
She'd been turned away from the Welly just an hour before she got into PR's car - her pals' night was just starting. In those temperatures, it seems plausible she may have been trying to return for her keys but struggling to go there on foot?
Interesting theory! I wonder (stereotype alert, apologies in advance!) whether a respectable Polish Catholic mother would want to be publicly associated with Ann Summers though? And whether a macho Polish bloke might not like the implication that he's not able to 'satisfy' his wife? However appreciate the pious stereotype probably doesn't apply to a younger generation of Poles living in the UK. A simpler explanation could be that a lot of women have sex toys, and most will tend to keep them within reach of the bed?
Lastly, and totally off topic
@motherofdaughters, can I recommend Stugeron? Transformed my travelling after decades of throwing up over coaches, buses and cars!)
