epa04229688 An undated handout picture released by Google on 28 May 2014 shows an artistic sketch of Google’s prototype of a self-driving car. Google has designed a vehicle that requires no steering wheel, no pedals and no driver. The internet technology giant said in a blog post on 27 May 2014, that 100 prototypes of the electric two-seaters that will still retain manual controls will be built and tested for safety beginning in mid 2014. Google has worked for years to develop self-driving cars that use sensors and computers to navigate streets, but the blog post confirmed speculation that it was manufacturing its own vehicles rather just modifying those made by other carmakers.
