While strolling by the lake today, I had a money-making idea, and I'd like to share it.

The lakeside scenery was beautiful, and the sunshine was lovely. There's a small square by the lake, and because it's close to nearby residential areas, many people bring their children to play there. It gets even livelier in the evening, mainly with families.

With this naturally stable flow of family traffic, I remembered a children's four-wheeled electric car I saw online, like the one in the picture below.

If I put a few in the square, when children want to play, some parents would be willing to pay to let their kids have some fun, given the reasonable price.

I did a simple cost and revenue estimate:

Cost:

One-time cost: Approximately $40-$80 each. It's best to buy different styles and designs, such as sports cars, Transformers, or Disney cars. Assuming an average of $60, you'd need at least 3, totaling $180.

Daily operating cost: Less than $1 per day. The cars need charging, but the power consumption is very low, almost negligible.

Revenue: Daily Revenue Estimation: Assuming 10 orders per day, tiered pricing can be used, such as: $1 for 5 minutes, $2 for 15 minutes, $3 for 30 minutes. At an average of $2 per order, daily revenue would be $20, and costs could be recovered in approximately 10 days.

What do you think of this idea?
