Hi guys! First, congratulations for the service, it is awesome! I’m trying to convince my boss that it is worth it to pay for a monthly subscription via paypal! I also have a suggestion: a possibility to add multiple cars. For example, in my company we have two delivery vehicles and we want to optimize the route for, say, 15 stops today, trying to balance it between both cars. That would be awesome! Thank you and good luck!
Hi there and thanks for the compliment. Your boss is the best boss in the world. Tell her/him that 
Multiple cars/days was brought up before and is on our list for future development. It is not an easy change, it’s rather complex and it will need quite some adjustments and effort. Therefore it’s not on our roadmap for the near future.
Update: we’ve a test set up for multiple routes:
