One possible approach would be to allow the vehicle with defined limits, such as:
• Short-term only (e.g., 48–72 hours for loading/unloading before or after a trip)
• Seasonal limits (allowed during certain months, not year-round)
• Frequency limits (e.g., may be parked at home X days per month)
• Not continuously stored (must be moved or stored offsite after a set period)
• Temporary parking before departure / after return only)
