I bet everyone of us have had a problem when you lose truck/trailer/car and it respawns. So i have a suggestion to add a new service that will get your vehicle back to you, so you dont have to go back to house/parking where your car respawned. It will be easy and you can continue your route. This service will be like towing assistance or something like that. You could type /tow then choose a vehicle from your cars list and wait like 20-30 IG minutes untill assistance will tow your vehicle to you. And then you will be charged some cash (~$3000 - $5000) This would not be able to do on mission obvious so people wont abuse it on tasks.
