I messaged her yesterday about a potential meet. She sent her number and said to WhatsApp. Which I did around 2pm and didn't get a reply. Then about 10:30pm got a reply which said "Hi, still available, how long do you want?" I just ignored it. Then, over the next 10mins I got 4 calls on WhatsApp and 3 more messages along with 2 normal calls and 2 txt's on my phone. Had to block her. She was going nuts, desperately trying to get hold of me right their and then. 6 hours after I messaged and at a pretty indecent time. I would avoid this one like the plague. It felt very much like drug related desperation for cash.
Good call. Even if it wasn't drug related, contacting someone on a phone at 22:30 is unacceptable.
And frankly deluded to think you were still interested, when you contacted her at 2pm.

Following up like that with so many messages/calls in a row does indeed indicate desperation rather than rational, considered thinking, whatever the reason behind it.
Well done for giving her a piece of her own medicine.
Pulling that together with a) punting in a car and b) doing it in a VERY public and risky place, says to me that she's got low inhibitions and a high appetite for risk taking. On that alone, I'd avoid her for fear of her or one of her associates robbing me for a trivial amount of cash. Definitely not the type of behaviour I like to associate with anyone I know or interact with.
She's blacklisted.
