how to not look / feel like an evil r*pist doing crack when doing night photos at 3am in dark parking lots

so i finally decided to take my camera out on one of my 3am night drives in my rural town tonight when disaster struck. i usually never see anyone on the road / at spots i wanna shoot when im driving, but i guess cause it’s a sunday night it was more busy tonight then usual. tonight’s spot was off a two lane road with a size able in a parking lot pull off area on this inter coastal mini-island near me with almost no lights on it. half of the parking lot is lit and the other half isn’t, so i pulled my car to one end of the parking lot, opened my sunroof, and turned my car off. i only took a couple shots before i saw a car coming up the road. i already felt like i looked like i was doing heroine in my car or disposing of a body so i was watching them hoping they wouldn’t pull into the lot, but then they did. then they didn’t stop at the lit half of the parking lot, they just kept coming. then they passed right behind me and i turned my car on and closed my sun roof which i feel made me look even more guilty like a scary p*dophile serial killer, but also i’m 18 and highkey not trying to get abducted by a scary p*dophile serial killer. does anyone with experience have any tips on how to be less suspicious without putting myself in harms way by getting out
