Greater Noida (UP), Feb 08 (ANI): Reacting on the APP Government’s ‘Odd-Even’ formula, Congress president Sonia Gandhi's son-in-law Robert Vadra on Monday said people had to face inconvenience because of the scheme. He added though there was less traffic on the road, but the level of pollution saw no difference. He further said that the hybrid and CNG vehicles should be used by people but the prices of these vehicles should be customer-friendly.
