How much does a driverless truck cost?

Clarifying questions
-By driverless truck do you mean no human intervention or partial? (Assuming fully autonomous!)
-By cost do you mean on-road price? (assuming yes)

Assumption: It is a standard size truck, the Tata ones we see.Average quality, basic features.

Cost = Cost of a normal truck + cost of the self-driving system - steering wheel, paddle, gear, etc. (neglected)
cost of self-driving system = Camera + Lidar + GPS + Internet + Computation + automatic break, speed, etc.
Camera*4 ~ 13000*4 (consider the quality and ruggedness)
Lidar*2~ 3000*2
GPS + Internet~ 4000
Computation(assuming on truck itself) ~ 15000
Automatic break, speed, etc. ~ 20000
Total~97000

Validation- Cheapest Autonomous car costs around 14 lacs.
Cost of Tata truck~ 20 lacs
Total cost ~21 lacs
