A speeding driver who had taken cocaine and ended up killing a church-going volunteer in a 60mph crash 'goaded' by another motorist, has been jailed.
Stephen Milligan lost control of his Nissan 350z while he chased after an Audi in front which kept slowing down and speeding up.
When the Audi accelerated around a bend, Milligan, of Rugby, Warwickshire, sped up but mounted the kerb and ploughed into Margaret Adams who was carrying shopping bags.
The 60-year-old married church volunteer was killed instantly after she was flung into the air and landed on the pavement.
When police arrived 56-year-old Milligan tried to blame the Audi driver for causing the crash, telling officers: 'I don't usually drive like a prat'.
A blood test showed Milligan had traces of cocaine in his system.
Milligan, admitted causing death by dangerous driving and was jailed for three years at Warwick Crown Court on Tuesday.

'You set off on a mundane journey which took you into the centre of Rugby.
'It is obvious the Audi slowed unnecessarily as it was going through the gyratory system and then accelerated away along Bilton Road, a road lined with residential properties.

'You were responding to the actions of another motorist who it might be thought has been fortunate in not facing any form of prosecution.
'As you approached a bend, as Mrs Adams was walking with her shopping, you accelerated, and as a result, in part because of the speed and in part because yours was a rear-wheel-drive car and the tyres were in poor condition, you lost control.
'Your car came off the carriageway onto
