Tipping car delivery drivers can vary depending on the circumstances and the level of service provided.

Here are some guidelines to consider:

Standard Delivery:

If you've ordered food or a small item for delivery, a tip of 10-20% of the total bill is generally considered appropriate. You can adjust the percentage based on the quality of service, the distance traveled, and your satisfaction.

Shipping Large Items or Furniture:

For larger items like furniture or appliances, consider tipping between $10 to $20 per person involved in the delivery. If the delivery involves a lot of stairs or other challenges, you may want to tip on the higher end.

Car Service or Ride-Sharing Delivery:

With ride-sharing services like Uber or Lyft, tipping through the app is common and typically ranges from 15% to 20% of the fare. If you're using a car service that doesn't have an in-app tipping option, a cash tip is appreciated.

Flower or Gift Delivery:

For flower or gift deliveries, a tip isn't always expected, but it's a nice gesture. You can tip $2 to $5 or more depending on the complexity of the delivery and your satisfaction.

Pizza or Food Delivery:

A tip of 10-20% of the total bill is standard for pizza and other food deliveries. Consider tipping on the higher end if the weather is bad or if the driver has to travel a long distance.

Grocery Delivery:

For grocery delivery services, it's common to tip between 10% and 20% of the order total, with a minimum tip of $5. Adjust based on the size of the order and the effort involved in the delivery.

 Towing Services:

 If your car has been towed, tipping isn't always necessary, but if you feel it's deserved, you can tip the     driver $10 to $20.

 Valet Parking:

If you use valet parking at a restaurant or hotel, a tip of $2 to $5 when your car is returned to you is customary.

Remember that tipping is a way to show appreciation for good service, and it should be based on your level of satisfaction and the circumstances. If the delivery driver goes above and beyond, it's always nice to reward their efforts with a more generous tip. If you're unsure about the appropriate tip amount, you can ask the delivery driver or check if there are any specific tipping guidelines provided by the delivery service.
