How does the engine decide between MRT and Grab?

The engine evaluates if the cost per minute saved by taking a Grab is worth the urgency. If you are in a storm or have high time sensitivity, it recommends Grab. Otherwise, it checks if the extra cost is less than $2 per minute saved.

Does weather affect the Grab cost?

Yes, you can use `get_weather_surge_multiplier` to see how much the fare increases. Storms have the highest multiplier, followed by rain.

Can I check if it is currently peak hour?

Yes, the `is_peak_hour` tool identifies if the provided 24-hour time falls within Singapore's morning or evening rush hours.
