Lightfoot Avis 

Dangerous. Completely inappropriate if you're doing a journey of more than a mile in a suburb.
Avoid.

[Edit to reply to Lightfoot's attempt at self validation]

Are you on drugs? I've driven all over the UK and most of Europe in the thirty seven years I've been driving. I'm licensed to drive pretty much anything other than tanks, ambulances and fire engines.
When your idiotic device tries to get you joining the A1 northbound at 40 miles an hour and wants to keep you at that speed for two miles. Because the camera hasn't seen a national speed limit sign. While HGV's are charging up behind you at 60mph.
How safe do you think that is?
This device is clearly made for people who do a couple of short journeys around town. It is totally inappropriate for anyone who drives over a distance or in any kind of professional capacity.
As for it's economic value. All that metal for engine repairs because you're constantly labouring the engine by not being able to shift through gears correctly. That's gonna be great for the environment.

Even accelerating from 40mph to 50mph in 6th gear on cruise control got me that sanctimonious "go steady" remark that is nothing short of insulting.
So it would appear then that Mercedes do not know how to correctly calibrate their vehicles to accelerate properly?

More times than none you lose on the putting wee game and I find that a few of the vans ive used the lightfoot stays amber way to long even after lifting your foot off ....

Pulling out of junctions id dangerous as you like to keep it in the green but in order to do that you really need to make sure there's nothing coming for at least a lorry lengths

Shows the info you want for easy access, love the giveaway entry's that go on too!

Very good app but still slow navigating between the apps.

Winner winner

If you're looking for a device that increases fuel efficiency across your fleet, Lightfoot may in some cases fit the bill. But since they changed the settings on my van I've gone from averaging 40mpg to around 35mpg. I'm sure this is due to me being in too high a gear just to stop Lightfoot moaning at me. It will however leave you with frustrated and distracted drivers.
I've been driving a van with it fitted for 2 years now and have always managed a weekly score of over 85
% which qualifies me as an "Elite driver". This allows me enter prize draws and lotteries. So far I've won just over £20, not much of an incentive to be honest.
The biggest problem with Lightfoot would appear to be how they measure "efficient" driving. I get an irritating voice shouting "Go Steady" when the device believes that I'm driving inefficiently. However by their support departments admission, the system is unable to know the road conditions, i.e.: wether you're going up a steep hill or not.
If I chug up hills with my foot flat to floor in 6th gear with the engine labouring inefficiently, then Lightfoot sits there quite happily and doesn't utter a peep. If I try to drive in an efficient manner and change down a gear, so that the engine is pulling cleanly, Lightfoot goes into something of tantrum shouting "Go Steady". My crime? going above 2500rpm it would appear. In fact going above 2500rpm in 3rd, 4th, or 5th gear is enough to receive a warning, regardless of traffic or road conditions. hardly indicative of a sophisticated driving monitoring system.
If you happen to drive in an area with lots of roundabouts, Milton Keynes for example, then be prepared for lots of shouting and warnings, as accelerating between roundabouts really upsets it.
I've raised the issues I experience with customer support e.g. getting a warning for joining the M1 from the M25 at 60mph in 5th gear (again I suspect this was simply because I touched 2500rpm in 5th).
I've pointed out that despite their claims that warnings are issued due to harsh acceleration, I'm getting them whilst accelerating gently but merely exceeding 2500rpm (the redline is 6500rpm). But they don't appear to want to acknowledge this and simply say that if you're score above 85% don't worry and ignore the warnings!!
In my experience Lightfoot is an annoying distraction that does nothing to improve driving standards, Fuel efficiency may increase, but fuel efficient driving is not necessarily good or safe driving.
You can see by their response that they will not accept that it gives you unwarranted warnings, even when you are driving in an efficient manner.I don't think many people would suggest 60mph in 5th gear is worthy of a warning, but Lightfoot do.
Again from their response, you can see that they don't issue warnings if you happen to exceed speed limits. All that matters is gaining a score of 85%, regardless of how you drive to achieve it.

Excellent Service

This helps me to drive more carefully and economically.
Helps me to drive more smoothly.

A Polite prompt service got the issue sorted immediately thank you.

Helping me to maintain high and professional driving standards through competition and accountability.

I had an issue that has been dealt with swiftly with a lot of understanding.

Just wanted to say I had an issue with my Lightfoot app and your team got me up and running in no time and hassle free, Thank you. I wanted to say having Lightfoot it's made me a better driver and saves me fuel.

Quick response and resolution

Great app. Easy to use

Promotes great driving incentives

Lightfoot is great for improving my driving, I feel like I've improved and became friends with the throttle since I've been using it. The app is easy to use and it was incredibly easy for me to set up my account.

Could have more incentive, a better chance to win? The last time I won before this was 3 years ago, and the prize isn't worth it, a couple of £'s

Quick response and responded to my issue effectively
