I do not think that you comment is correct reg claiming LTA, where you have mentioned that bill from a car rental company is a valid document for claiming LTA. As far as I know, as per the rule -
Where the place of origin of journey and destination or part thereof are not connected by rail and the journey is performed on or after 1st day of October, 1997 between such places, an amount eligible for exemption shall be -
where a recognised public transport system exists, an amount not exceeding the first class or deluxe class fare, as the case may be, on such transport by the shortest route to the place of destination; and
where no recognised public transport system exists, an amount equivalent to the air-conditioned first class rail fare, for the distance of the journey by the shortest route, as if the journey had been performed by rail
This means you can produce car rental bill only if there is no recognised transport system exists on the route and even then reimbursement will be on the basis of distance travelled calculated at 1st AC train fare.
