You're absolutely right! The booking flow should check vehicle availability based on the selected dates first. Let me fix the booking process to show available vehicles only after selecting the date and time range.

Perfect! I've fixed the booking flow to follow a more logical sequence:

Updated Booking Flow:

Step 1: Select Date & Time

• Users first select their desired booking dates and times
• Shows duration calculation
• Validates that end date/time is after start date/time

Step 2: Select Available Vehicle

• Shows only vehicles available during the selected time period
• Displays the selected date range at the top
• Filters out vehicles that are already booked during that period
• Shows "no vehicles available" message if none are free

Step 3: Booking Details

• Driver options, passenger count, purpose
• Document uploads
• No longer includes date/time selection (moved to Step 1)

Step 4: Confirmation

• Final review of all booking details
• Submit booking

Key Improvements:

1. Better UX Flow: Users know availability before getting attached to a specific vehicle
2. Real Availability Check: Only shows vehicles that are actually available for the selected dates
3. Clear Progress: 4-step process with logical progression
4. Validation: Proper date/time validation before proceeding
5. Fallback Options: If no vehicles available, easy to go back and select different dates

The system now properly checks vehicle availability based on the selected booking period, making the booking process much more user-friendly and realistic!
