Avoid c-charge fines automatically

GPS-toting KenBuster pays your congestion charge straight away - so you won't fall foul of fines.
Absent-minded London motorists should definitely give the KenBuster a look. This newly-launched gizmo sits in your car and uses GPS tracking to determine when you've entered the congestion charge zone.

If you've done so at a chargeable time and day, an automatical payment is made to Transport for London - meaning that you don't have to remember to make the payment yourself later on. So forgetting to pay the charge - like 6% of motorists do every day - won't result in you getting slapped with a fine.

Every day the KenBuster sends you a text message informing you of any payments made, and you can also track transactions on the website.

The device is available to preorder now, and will be out before Christmas. It can be bought for £50 then £8 a month for 12 months, or for a one-off £200 for unlimited use forever (and "tired" KenBusters will be upgraded for free).

Sounds like a pretty smart idea, but Transport for London might not like it - according to KenBuster they make an astonishing £65m a year (31% of their income) through congestion charge fines.
