Out of curiosity, why not?
There are too many variables involved to leave it to a satnav.
There are RORO (roll-on, roll-off) ferries that cover different routes - they may put you nearer your destination but take longer. They all run on different schedules and have different costs. When I used to use them on a motorbike, there was always room for a bike and you could basically turn up & go, but in a car at peak times you might have to wait for a couple of sailings or book in advance. There's also the consideration that they may not run regular crossings 24h/day, or with fewer sailings at night.
There's also the Channel Tunnel (which I've not used myself). That takes a different amount of time again, goes to a different destination and has a different cost.
