Tnt minecart buff in bedrock edition

Dear microsoft I have a slight inconvenience with tnt-minecarts as I have noticed in Java edition if you hit a tnt-minecart with a flame bow or with a arrow that's on fire it explodes like it's supposed but the mechanics of java are too different from bedrock as the Tnt-minecart deals more damage based on the speed of the arrow. however in bedrock edition there is no such thing as it does 2 hearts of damage. This is really crucial to a pvp technique named tnt-minecarting if the Tnt-minecart are such low damaging it is no use for using them making them useless until used in vain i would like mojang to make the Tnt-minecart mechanism the same as in bedrock
