4. Electric Taxi

First the good news: the UK's first electric taxi is powered by lithium-ion batteries, has a range of around 100 miles on a single charge and has a top speed of 60mph.

It can carry up to six passengers and also provides full wheelchair access.

Now the bad news: there's no more noisy diesel engine to drown out the random philosophies of cabbies everywhere.

'The state of schools today? Victoria Beckham, mate.'

Lord help us all.

The taxi costs from 39,450 and its maker, Allied Vehicles, expects running costs to be around 500 a month plus VAT, so there'll be no need to tip.

Chances of seeing it on the road It's going to happen one day, although not too soon.
