OK, serious advice, step by step:
Park the car. As you’re putting it in park, say, “Let me grab your door,” and get out of the car before she gets a chance to say it’s not necessary (I wouldn’t, but some women will). This eliminates the chance for the awkward “So...” moment if you’re both shy.
If she’s gotten out of your car before you get to her side, say, “Let me walk you up,” and start walking. The only reasons for her to say no would be (1) the date had gone very badly and/or you were grabby (don’t be), or (2) she’s confusing gentlemanly behavior for that ridiculous “male microaggression” notion that comes from a crappy education.
If (1) or (2) are true, you can get back in your car knowing you didn’t miss out on anything.
When you get to her door, you tell her you had a very nice time, whether it’s tru or not. If it is true, tell her why (enjoyed the conversation, her sense of humor, her running stats, etc.)
Step back, open your arms for a hug, and give her a big smile. A hug is non threatening. So is a kiss on the cheek. So is asking whether you can see her again.
Trying to kiss her is OK if her body language says she’d like you to (trying to kiss her is OK, period, because most women will find a polite way to let you down if you’d misread the signals, but I’m assuming you’re shy).
If you are completely at sea as to whether she likes you or not, stick with the hug and the kiss on the cheek. If you like her and she likes you, you’ll see her again, and by then you’ll read her better.
If you get an asshat treatment despite being a gentleman, remember - that’s not on you. We women can get nervous, too, even if we’re assertive - especially if we like you. But it’s never OK to be an ass to a guy unless he seriously, in-your-face earns it. And if a guy earns it, a real woman Ubers it home immediately and that’s that.
You sound like a nice guy. You’ll be OK.
