Car Interactions

This is the BIGGEST (and possibly the last) update for Car Interactions.
Don't forget to update my other mods as well if you use them!

Update: 10/31/2026

• New Features (Thanks to Thequesh for the idea!):
  - Sims can now eat in the car.
  - Sims can now use their phones in the car.
  - Sims can now read books in the car.
  - Sims can now take photos in the car.
  - Smoother nap animations (without Sims disappearing).
  - Forget the rest. Probably good changes.

No matter where your Sims are headed, be it a fun road trip, a lively party at a friend's house, or a visit to relatives who might be short on beds, the car is always part of the adventure. This mod adds a few more interactions to vehicles: Sims can sit in the car, take a nap, or turn the headlights on whenever they feel like it.
Features:

- Sit in the car: Sims can sit in any seat, driver's or passenger's, and just relax for a while. Fun goes up while they're inside.
- Nap in the car: Sims can take a nap in the parked car (or even in a moving one, if they're a passenger), slowly restoring energy with a custom sleeping animation.
- Toggle headlights: You can turn the headlights of a parked car on or off. They stay on until you switch them off or someone drives the car.
- Traits matter: Sims with the "Vehicle Enthusiast", "Adventurous", or "Loves the Outdoors" traits get better rest from car naps and won't wake up with a sore back. Sims without these traits aren't always so lucky.

Compatibility:

- It's a lightweight script mod. It doesn't override any core game files or write to your save file, so it's 100% safe to add or remove anytime. Please note, as of the 08/15/2026 update: the moodlets are stored in your save. If you remove the mod, the game discards them automatically on the next load, so uninstalling stays clean.

XML Tuning (via s3pe):

- kSitDurationMinutes: How long (in Sim minutes) a Sim sits in the car. Default: 120. Set to 0 to sit until canceled.
- kNapMaxMinutes: How long (in Sim minutes) a Sim naps. Default: 0 (sleeps until fully rested).
- kEnergyRateNormal: Energy restore rate for ordinary Sims. Default: 0.85.
- kEnergyRateTraited: Energy restore rate for Sims with the listed traits. Default: 1.2.
- kTalkChancePercent: The chance (in %) that Sims in the car will start talking. Default: 75.
- kLikingPerTurn: How much relationship Sims gain from talking in a car. Default: 0.75. (Intentionally set low to prevent exploiting fast friendship gains. Recommended range: 0.75 to 1.3).

Install:

- Just drop CarInteractions.package and CarInteractionsSleepAnim.package into your Mods/Packages folder. Done!
