Mafia II

This achievement is very simple and doesn't take long at all (maximum 1 hour)

The fastest way I found to do this is to firstly, pick a car of your choice, preferably a fast one (I chose the Roller GL), and then just drive up and back down the Brooklyn Bridge!

You'll have to go up and down the bridge 30 times each for 50 miles.

I done this on chapter 11 while having Henry in my car, it doesn’t matter when you do it but there are no interruptions in this chapter.

If you are close to wrecking you car by crashing a few times, there is a garage on the right side of the Bridge very close, just repair it there.

You can use speed limiter if you like to be on the safe side of your driving..but who wants to be safe in a video game eh? plus it will nearly take double the time to get your 50 miles, just make sure to brake early when approaching the end of each side of the bridge.

Also I found this really helpful video on Youtube so thats a second option if the above doesn't suffice.

Hope this helped and have fun!

50 miles = 80.4672 km

So as everyone say: just pick a car in the beginning and drive each chapter with that car. You can pick this car also and drive a long end while combine it with "Cruise Control" to make a lot of distance in one time.

If you haven't gotten this by the last chapter, go to your garage and look for the car that you have the most miles on. It will tell you in the break down of that particular car's stats under Distance Traveled. Pick that car and get on the highway. If you figure out the route that takes you around the whole map, it is about 7 - 8 miles in distance.

The route that I took was crossing the bridge in Uptown, taking a right in Hunter's Point and staying on that road to get on the highway in Highbrook.

i got this achievement when i was searching for the wanted posters. just use the same car and u will get it. The wanted posters took me a lot of time to find by the way. Hope it helps

If you choose to just drive all 50 miles in one go just remember that if you crash and die you have to start all over again. I found this out the hard way. You will still have the miles in your statistics but the car will reset back to how many miles were on it at the begining of the chapter.

Straight forward really i got this in the middle of Chapter 14 when i had to go round robbing stores and crushing cars to make money, instead of doing this i went round and collected all the wanted posters as this was an ideal time to have the whole map to myself. Basically pick a car from your garage that you have done a few miles in and use that one as it will unlock quicker. Now make sure you dont run out of fuel and don't blow the vehicle up as you will have to start all over again. It unlocked for me on 51 miles.

How I got this was just using the Jefferson Provincial that you are forced to steal in the beginning of the game........whenever I was forced to use a certain car for a mission, I would just use it until I was able to switch cars, then ran home grabbed my Jefferson and finished the rest of the chapter with no "out of the way" routes, the cheevo popped naturally on the way to the Hillwood Observatory in the last chapter..........

A good way to do it that I wish I'd thought of BEFORE I'd beaten the game is this: As has been stated, pick a car to focus on and use it as much as possible. Then, every time you're prompted to go home and go to bed, don't. Instead, drive your chosen car around for about five miles (two rounds on the freeway should do it) before turning in.

Doing this, you should barely have to grind this thing at all when you run out of story.

Follow the instructions in this video.
You just have to keep driving on the highway till you achieve the achievement.

This achievement took like an hour, just keep driving till the achievement pops up. Note!: Drive to garage and check your stats immediatly after driving on the highway 5 times. Then you should be close to your goal!

None of these solutions on here have mentioned this way of getting it done relatively fast as far as I can see so I'll explain and try and make it as brief as possible.

In Chapter 8 towards the end you will have to drive a hot rod to Derek's Shipyard, first instead of doing that, park the hot rod somewhere (Don't worry you won't lose your hot rod as it stays marked as red on the map so you can go back and pick it up later) take any other fast car to the docks first off such as a Lassiter Series 75 Hollywood or a Beverly Kingfisher, (Look around for these, parked or driving, if you have trouble identifying them, look at the picture solution for The Exporter Achievement for a frequent spawning location for the two cars) sell one of the mentioned cars there in order to have enough to fully tune or upgrade your hot rod to Sports level performance. Once done, look on your map for the nearest bodyshop and once inside, tune the hot rod to the maximum level which is sport level and then drive it towards the main bridges at the center of the map.

If you do this then try go as fast as possible on the bridges but if you see the end of either side of the bridge, make sure to hit the handbrake otherwise you risk dying and having to restart at before you did all this, remember to keep doing laps of the bridges and as fast as possible in order for you to cut down time for this achievement. If you die or screw up any other way for example, actually blowing up the hot rod then the last checkpoint is when you're about to hijack the hot rod for the mission. I know its not too far away but its a pain in the ass to have to start from there again and your miles will reset on this car but not in statistics but that doesn't count towards the achievement, it has to be miles on this one car or any other car in the game. It has to be accumulative on one car only and not combined from different cars unfortunately.

You could risk doing the wall breach glitch as mentioned for the 1,000 miles achievement in the Jimmy Vendetta DLC guide/solutions but you won't be able to keep track of your miles as you can't store this car in your apartment's or Joe's garage as its a main part of the current mission you're on unfortunately. It still would of been nice if you could do so temporary but there's no use crying over spilled milk.

I hope this solution is good enough for you and many others!

I doubt when doing this you will be constantly focused and may drift in and out of gameplay and anything else you are doing (For me it was films). So I'd suggest using a car with a lower top speed to prevent you from crashing, a severe crash (resulting in death) means you have to start from where you were in the first place...

Circle the entire map, from Brooklyn Bridge, looping round the highway across the map.

For me I had to circle the map around 8-11 times for the achievement to pop, this was also used with a car I have in my garage in chapter 10, which gives the car extra mileage from earlier chapters so it may be more times for you.
