Are you sure the car is the reason for your failure? Could it be that you're scapegoating the car to protect your ego? We've all been on dates that went well only to be ghosted or get the "no romantic connection" line later.
Women are so fickle you simply can't judge her level of interest based on how she acts on the first date. This is particularly true of women you meet on apps. I've had women tell me that they really enjoyed my company and were looking to seeing me again only to completely vanish afterwards. I've had a woman initiate a kiss close only to tell text me the following day that she didn't feel there was a romantic connection (and no, I don't have bad breath). It's just how it is.
I have been on dates like this before in the past so i like to think i can recognise IOI's
So her interest was moderate rather than super high like had i walked her to the station i could escalate kino
I just felt bad cos it is -3C outside so thought what the hell give her a lift back, now i know not to gentlemanly as it'll just backfire
But if i think through the date the convo i feel i could have done things better moved it into better topics etc
I just looked at her reaction when we got outside and saw my car and that told me enough she was not interested anymore
